8/12/2026 – This is a long post with four Prompts/Responses with ChatGPT that began with the idea that James and John sons of Zebedee, were “mending the nets,” and that does not sound like the more strenuous work of deploying and retrieving them. Could that be an indication of their youth? That lead into prompts digging deeper into the fishing and how Simon and Andrew were “casting nets” whereas the Greek word for the net James and John were tending was generic. IMO the fact Zebedee had hired help was that they were using a seine net that requires more men. Use of seines is also discussed below.
PROMPT – What do critical bible scholars say is meant by the phrase “mending the nets” in the verse “Immediately he called them; and they left their father Zebedee in the boat with the hired men, and followed him.” Mark 1:19–20. Cite all sources in line.
In Mark 1:19, the phrase “mending the nets” is generally understood by critical biblical scholars as a literal description of ordinary fishing work, not as a hidden theological metaphor. The Greek, however, gives the expression a little more nuance than the English word “mending” suggests.
The Greek word behind “mending”
Mark writes:
“As he went a little farther, he saw James son of Zebedee and his brother John, who were in their boat mending the nets.” — Mark 1:19 NRSVUE
The verb translated “mending” is καταρτίζοντας (katartizontas), from καταρτίζω (katartizō). Its fundamental sense is to put something into proper condition, restore it, adjust it, make it complete, or prepare it for use. When used with fishing nets, “repairing,” “mending,” “putting in order,” or “preparing” are all legitimate translations.
This is why English translations differ:
NRSVUE: “mending the nets”
NIV: “preparing their nets”
CSB: “putting their nets in order”
CEB: “repairing the fishing nets”
NLT: “repairing their nets”
Darby: “repairing the trawl-nets”
So, strictly speaking, “mending” is somewhat narrower than the Greek. The verb can encompass the whole process of getting the nets back into proper working condition.
What were James and John actually doing? The most straightforward historical reading is that James and John were performing maintenance on their fishing gear.
Fishing nets were valuable equipment that had to be kept in usable condition. A net could become damaged during fishing, and fishermen needed to repair, straighten, arrange, and otherwise prepare it for subsequent use. The Greek vocabulary itself supports this practical sense: the same verb can mean “repair,” “restore,” “adjust,” or “put in order.”
There is also an interesting observation in the scholarly discussion of the word. James Hope Moulton and George Milligan, in The Vocabulary of the Greek Testament, note that the verb can have the sense of preparing something for its intended use. They also record an alternative interpretation of Mark 1:19—folding or stowing the nets rather than literally repairing them. That interpretation was based on an ancient scholion explaining the Latin componentes as either “stuffing” or “folding” the nets.
Thus, “mending” should not necessarily be pictured as James and John sitting there sewing up a large hole in a net. They could have been repairing damaged sections, straightening the net, arranging it, or otherwise making it ready for fishing.
Why does Mark mention this seemingly mundane activity? This is where the passage becomes significant for understanding Mark’s literary technique. Mark has just described Simon and Andrew as actively casting their net into the sea:
“As he walked by the Sea of Galilee, he saw Simon and Andrew the brother of Simon casting a net into the sea, for they were fishers.” — Mark 1:16 ASV
Jesus tells them, “Follow me,” and they immediately abandon their nets and follow him. Mark then moves a little farther along the shore and finds James and John doing the other major part of the fishing operation—getting their nets ready.
This creates a deliberate parallel:
Simon and Andrew
→ casting their nets
→ Jesus calls
→ they leave their nets
→ follow Jesus
James and John
→ putting their nets in order
→ Jesus calls
→ they leave their father/business
→ follow Jesus
The repetition reinforces Mark’s theme of the immediacy and radical character of Jesus’ call.
The scholarly commentary available on Mark recognizes this parallel. For example, R. C. H. Lenski observes that the two pairs are presented in corresponding situations: Simon and Andrew are actually fishing, whereas James and John are repairing their nets. The two participles describing their activities function as a deliberate parallel in the narrative.
The reference to “the hired men” in Mark 1:20 is particularly important:
“Immediately he called them, and they left their father Zebedee in the boat with the hired men and followed him.”
This makes it unlikely that Mark is portraying James and John as merely two impoverished fishermen with nothing to lose. The presence of hired workers indicates that Zebedee’s fishing operation was substantial enough to employ additional laborers. The NET Bible’s textual note accordingly regards the boat as potentially belonging to the family and observes that the hired workers in v. 20 support that inference.
[My observation – Given the 5-person “crew” described and sufficient nets to warrant so many, there must have been more than one boat. James and John would have been in one of them. “Mending” or tending would include removing fish, removing debris, as well as repairs.]
That makes the sequence more striking. James and John aren’t simply leaving a damaged fishing net behind. They are abandoning a functioning family fishing enterprise and their father, while other employees remain to continue the work.
That is one reason Mark’s mundane description of “mending the nets” is important: it establishes what they were doing immediately before Jesus called them away from their ordinary economic life.
Is “mending the nets” a metaphor for the disciples being “mended”?
There is a temptation to read the passage symbolically because καταρτίζω has metaphorical meanings elsewhere in the New Testament. For example, it can mean “restore,” “equip,” “prepare,” or “make complete” in passages such as Galatians 6:1, Hebrews 13:21, and 1 Corinthians 1:10.
But critical scholarship generally does not treat Mark 1:19 as saying that Jesus found James and John spiritually “broken” and was about to mend them. That would be an extrapolation from the broader semantic range of the Greek verb rather than something Mark actually signals in this passage.
The immediate object of the verb is “the nets”:
καταρτίζοντας τὰ δίκτυα
“mending/putting in order the nets”
So the primary meaning is straightforwardly fishing-gear maintenance.
There is nevertheless a literary irony: Jesus is about to take two men who are putting fishing equipment into proper condition and redirect them toward a completely different vocation. Mark immediately connects their fishing occupation with Jesus’ call of disciples. Simon and Andrew have just been told that Jesus will make them “fishers of people” (Mark 1:17). James and John are then summoned without receiving a separate explanation of their new vocation.
One particularly interesting distinction between Mark and Matthew
Matthew preserves essentially the same scene:
“he saw two other brothers, James the son of Zebedee and John his brother, in the boat with Zebedee their father, mending their nets; and he called them.” — Matthew 4:21
Thus the “mending” detail isn’t something that Mark invented independently for a theological wordplay; Matthew reproduces it as part of the traditional call narrative.
But Mark makes a subtle narrative change in the surrounding material. In Mark, James and John are “in their boat”, while Zebedee is mentioned only in the next verse, when the brothers leave him with the hired men. This helps establish the economic setting: they are working within their father’s fishing business, and there are employees besides the family.
Bottom line
The best critical-historical reading is:
“Mending the nets” means that James and John were engaged in the ordinary maintenance and preparation of their fishing nets—repairing, arranging, straightening, or otherwise putting them into usable condition.
It is not necessary to interpret the phrase as a symbolic statement about Jesus spiritually “mending” the disciples. The symbolism, if one wants to speak of symbolism at all, occurs at the larger narrative level: men engaged in the ordinary business of fishing are suddenly called away from their livelihood to become Jesus’ followers.
And the detail is actually quite useful historically. Combined with the reference to “hired men,” it suggests that James and John’s family was operating a relatively substantial fishing enterprise, rather than the story depicting four isolated subsistence fishermen. Mark’s emphasis is therefore not merely “poor fishermen leave their nets,” but disciples abandon a functioning family occupation and even their father’s business when Jesus calls them.
One further point is worth noting: the Greek does not require us to envision them literally sewing torn nets at that moment. “Putting the nets in order/preparing the nets” is probably the safest way to capture the full range of καταρτίζω in this context.
PROMPT – Is there any evidence that the act of “mending the nets” one for younger workers who do not have the strenght to work the nets in the water?
Yes—but there is no good evidence that “mending the nets” in Mark 1:19 specifically meant work assigned to younger or weaker members of a fishing crew because they lacked the strength to handle the nets in the water.
There is, however, some evidence that makes your proposed scenario plausible as a general feature of fishing labor, and it is worth distinguishing that from what we can actually infer about James and John.
What the evidence does establish. Mark presents two different activities:
Simon and Andrew: “casting a net into the sea” (Mark 1:16)
James and John: “mending the nets” (Mark 1:19)
And immediately afterward Mark says that James and John left “their father Zebedee in the boat with the hired men” (1:20). The NET translation notes specifically observe that the reference to hired workers indicates that Zebedee’s family operated a fishing business with employees.
The distinction between the two activities is therefore real: casting/working the nets in the fishing operation and maintaining/preparing them were different tasks.
But Mark does not say that James and John were mending the nets because they were physically incapable of fishing. There is evidence that net repair could be a task for younger workers. This is where your hypothesis becomes interesting.
The FAO’s historical and ethnographic survey of labor in fishing communities reports that children and young people can perform a wide range of fishing-related tasks. These include casting and pulling nets, but also, particularly after returning to shore, cleaning nets and repairing fishing gear. The report even provides photographic documentation of a young boy repairing fishing nets.
That establishes an important general principle: Net repair is a task that can be performed by younger workers and does not necessarily require the physical strength required for hauling or operating heavy nets. But that evidence is modern and cross-cultural. It cannot by itself establish that this was the labor arrangement in first-century Galilee.
What about the physical demands of Galilean fishing? Here we have to be more cautious.
The traditional picture of Galilean fishing involved different kinds of nets and different fishing techniques, and some operations could involve substantial physical effort. Mark’s description of Simon and Andrew “casting” a net is particularly important. They are actively engaged in fishing when Jesus encounters them. James and John, by contrast, are in the boat working on the nets.
The Greek actually gives us some flexibility here. Mark uses καταρτίζοντας (katartizontas) for what James and John were doing. The NET text translates it “mending,” while other translations render the activity as “preparing” the nets. Consequently, we should not automatically picture James and John sitting down and sewing up holes in a net. They could have been repairing, arranging, preparing, or putting the nets into proper condition for use.
There is an important socioeconomic clue. I think the strongest argument for investigating your suggestion is actually Mark 1:20, rather than the word “mending.” Zebedee has hired men. That means we should probably imagine something closer to a family fishing enterprise with a division of labor rather than four men all doing exactly the same physical work.
A possible structure would have included:
- Zebedee as the senior/family head;
- James and John as members of the family workforce;
- hired laborers;
- different tasks associated with operating and maintaining the boats and nets.
The NET translators specifically point to the hired men as evidence that the boats were probably part of Zebedee’s family’s fishing operation. That makes it quite reasonable to ask whether age, strength, experience, and status within the fishing operation affected which tasks an individual performed.
But that is an inference—not something Mark tells us. Could James and John have been the younger workers? Possibly, but there is a problem with making that conclusion.
The text does not identify James and John as children or adolescents. They are called “the sons of Zebedee”, and they appear to be functioning as members of the family business. Mark subsequently treats them as adult disciples capable of leaving the business and following Jesus.
Matthew’s parallel is even more explicit about the family arrangement: James and John are “in the boat with Zebedee their father, mending their nets” (Matt. 4:21).
So the evidence does not allow us to say: James and John were mending the nets because they were too young or weak to handle the fishing. That goes beyond the evidence.A more defensible formulation would be:
James and John may have been performing a less physically demanding component of the family’s fishing operation while Zebedee and/or other workers performed the more strenuous fishing tasks.
That is quite plausible within a family enterprise, but we don’t possess a first-century Galilean source that explicitly describes such an age-based division of labor. One thing I think is particularly significant; your observation becomes more interesting when we put Mark 1:16–20 together:
- People Activity when Jesus encounters them
- Simon & Andrew Casting the net
- James & John Mending/preparing the nets
- Zebedee In the boat with the hired men
Mark may therefore be giving us a glimpse of different stages of a fishing operation and different workers performing different tasks. But I would stop short of saying that Mark is deliberately telling us that younger men were assigned to net repair because they lacked the strength for fishing. There simply isn’t sufficient ancient evidence to make that a scholarly conclusion.
In fact, the evidence we do have suggests something slightly broader and potentially more interesting: fishing was a cooperative economic enterprise requiring multiple kinds of labor, and Mark’s reference to the hired workers gives us a rare glimpse of that organization. The FAO evidence demonstrates that net maintenance is indeed the sort of work that can be performed by younger workers, but it does not establish that this was the particular arrangement at Zebedee’s business.
So my assessment would be:
- Historically possible: Yes.
- Supported by general fishing practice: Yes.
- Supported specifically for first-century Galilee: Weakly/inferentially.
- Explicitly supported by Mark: No.
- A position held by critical scholars as an established interpretation of Mark 1:19: I have not found evidence for that.
If you are asking this because you are trying to determine whether Mark’s description might give us a clue about the relative ages of James and John compared with Simon and Andrew, that is a more interesting question—and the evidence can be pushed considerably further in that direction, although with important qualifications.
PROMPT – Does Mark’s description give us a clue about the relative ages of James and John compared with Simon and Andrew? Cite all sources inline.
Yes, but only as a weak and indirect clue. Mark’s description can reasonably raise the possibility that James and John were younger or less senior members of Zebedee’s fishing operation than Simon and Andrew, but it cannot establish that conclusion. I would distinguish between what the text actually gives us and what can reasonably be inferred from it.
- Mark deliberately describes different jobs
Mark’s sequence is quite precise:
- Simon and Andrew are “casting a net into the sea” (1:16).
- They immediately leave their nets.
- Jesus goes farther and sees James and John “in the boat mending the nets” (1:19).
- James and John then leave their father Zebedee “in the boat with the hired men” (1:20).
The NET translators identify the fishing as net fishing, involving nets with substantial weights around their perimeter. Thus the activities Mark describes were not merely different ways of saying “they were fishermen”; they refer to different tasks in the fishing operation.
That makes your question legitimate: could the division of labor reflect differences in age, strength, or status?
- The text itself does not identify James and John as younger
This is the major limitation.
Mark never says:
- James and John were younger;
- Simon and Andrew were older;
- James and John were apprentices;
- James and John were unable to handle the nets in the water.
Consequently, no critical scholar can responsibly derive their relative ages simply from Mark 1:19.
In fact, the Greek verb καταρτίζω (katartizō) does not specifically mean “doing the easier work.” It has the sense of putting something in order, preparing, restoring, or repairing. So “mending the nets” does not inherently imply a subordinate or less strenuous job.
- But the combination of details makes a younger/less senior role plausible
This is where I think your observation has real interpretive value.
Mark gives us:
- Simon and Andrew → actively fishing
- James and John → preparing/repairing the equipment
- Zebedee + hired workers → continuing the business
- That could reflect a division of labor within a family fishing enterprise.
And Mark’s mention of “hired men” is particularly significant. It indicates that Zebedee’s operation wasn’t simply a father and two sons working alone. There was an organized labor force. The parallel material in Luke 5:10–11 also portrays Zebedee’s operation as sufficiently substantial to involve multiple boats and partners, although Luke’s account is a different version of the call tradition. The combination is consistent with a commercial fishing operation rather than isolated subsistence fishing.
So it is reasonable to hypothesize that different members of the operation performed different jobs according to their experience, age, or physical ability. But that’s an inference from the socioeconomic setting, not something Mark explicitly tells us.
- There is another potentially important clue: Mark calls them “the sons of Zebedee”
Notice the difference in the two pairs. Mark initially says:
“Simon and Andrew, Simon’s brother”
Then:
“James, the son of Zebedee, and John his brother”
And when James and John leave, Mark says they leave “their father Zebedee” behind with the hired men. This makes the family structure particularly prominent in the second pair.
That could mean James and John were still functioning as sons working within their father’s enterprise, whereas Simon appears to have had a somewhat more independent position. This becomes more interesting when we bring in other Gospel evidence.
- Simon appears to have a somewhat more mature household status
Mark 1 itself doesn’t give Simon’s age, but Mark subsequently tells us that Simon has a wife/household: Jesus enters Simon and Andrew’s house and finds Simon’s mother-in-law sick (Mark 1:29–31). That is a genuine difference between Simon and James/John in the narrative.
It doesn’t prove Simon was older. A man could marry relatively young in first-century Jewish society. But it establishes that Simon had already established a marital household, whereas Mark’s narrative repeatedly places James and John in relation to their father and his fishing enterprise.
Thus, if we’re trying to reconstruct relative social maturity, the evidence leans somewhat toward Simon being more established than James and John.
I would not extend that conclusion to Andrew. We don’t have comparable information about Andrew’s marital status.
- There is a much more interesting clue concerning James and John specifically
The later Gospel tradition gives us something that Mark 1 does not.
In Mark 10:35–37, James and John approach Jesus with their request for positions of authority, and their mother appears in Matthew’s parallel (Matt. 20:20–21). Some interpreters have taken the mother’s involvement as evidence that James and John were relatively young. But this is controversial, and it does not establish an age.
More importantly, modern critical scholarship has become increasingly cautious about extracting age information from seemingly minor terminology in Mark. For example, Isaac T. Soon’s 2023 study of Mark 15:40 argues that “James the little” (ὁ μικρός) should not automatically be interpreted as “James the younger”; the term is more likely a nickname referring to height or possibly affection/childhood.
That illustrates an important methodological point: ancient descriptions that sound like age indicators frequently aren’t reliable age indicators.
- What I think we can legitimately infer
I’d rank the possibilities this way:
- Proposition Evidence
- James & John were fishermen Strong
- They worked in Zebedee’s family business Strong
- Zebedee’s operation employed hired labor Strong
- Different fishing tasks were being performed Strong
- James & John were doing net maintenance/preparation Strong
- Net maintenance could be assigned to less physically demanding labor Plausible
- James & John were younger than Simon & Andrew Possible, but unproven
- James & John were specifically assigned net work because they were too young/weak for fishing No direct evidence
- Simon was probably more socially/maritally established than James & John Reasonably supported
- Andrew was older than James & John No meaningful evidence
- There is an important alternative explanation
We shouldn’t assume that mending nets was necessarily the “easy” job. If the nets were large, weighted fishing nets, repairing and arranging them could itself be demanding work. The NET notes that the fishing technique involved nets with heavy weights around their perimeter.
Moreover, James and John could simply have been doing the job required at that particular moment. Simon and Andrew happened to be casting their net when Jesus encountered them; James and John happened to be preparing theirs. So the sequence could be temporal rather than hierarchical: one pair is fishing → another pair is preparing equipment → Jesus calls both.
That is probably the safest reading of Mark by itself.
ChatGPT’s conclusion
I would not use Mark 1:19 as evidence that James and John were younger than Simon and Andrew. That claim is too strong. But I would use it as one piece of circumstantial evidence in a larger argument that James and John may have occupied a somewhat different—and potentially less senior—position within the fishing enterprise.
The most interesting combination is:
James and John + their father + hired workers + net preparation
versus
Simon and Andrew + active fishing
and then the additional evidence that Simon already had a wife and household.
Taken together, that makes it quite reasonable to investigate the possibility that Simon was older/more established and James and John were younger members of the fishing workforce. It just cannot be demonstrated from Mark 1:19 alone.
And I think there is an important distinction from the popular claim that “John was a teenager.” The evidence doesn’t get us that far. At most, it gives us a probability gradient: Simon may have been more mature/established than James and John; James and John may have been relatively young; but their actual ages remain unknown.
If you’re interested in pursuing this, the next useful step would be to
examine all of the age clues for Peter, Andrew, James, and John across Mark, Matthew, Luke, John, Acts, and the early noncanonical traditions and see whether they collectively produce a defensible relative-age model. That would be much stronger than relying on the “mending the nets” passage alone.
PROMPT – When the author of Mark says Simon and Andrew are “casting a net into the sea” (1:16) is the greek word translated as “casting” that same as used for placing a seine net and for throwing a cast net? Was net like the modern cast net used by those fishermen? Cite all sources in line.
Yes. Mark’s Greek gives us considerably more information than the English “casting a net” suggests. In fact, the Greek strongly indicates that Simon and Andrew were using a cast net—a circular hand-thrown net—rather than a seine/drag net.
1. Mark uses two different Greek words: the verb and the noun
Mark 1:16 reads:
ἀμφιβάλλοντας ἐν τῇ θαλάσσῃ
amphiballontas en tē thalassē
The verb ἀμφιβάλλω (amphiballō) is the word translated “casting.” Its basic idea is “to throw around” or “cast around.” In Mark 1:16 it is used absolutely, with the object supplied by the accompanying noun in the next grammatical construction: ἀμφίβληστρον (amphiblēstron), “a casting net.”
The noun is particularly important. ἀμφίβληστρον is not the ordinary generic Greek word for “net.” Lexicons distinguish it from other fishing nets and specifically define it as a “casting-net.” Abbott-Smith’s lexicon, for example, distinguishes:
- ἀμφίβληστρον = casting net
- σαγήνη (sagēnē) = drag/seine net
- δίκτυον (diktyon) = general term for a net.
So yes, the Greek terminology itself distinguishes the net in Mark 1:16 from a seine.
2. The net in Mark 1:16 corresponds very closely to a modern cast net
The ἀμφίβληστρον was a net thrown by hand over the fish. The description in the Encyclopedia of the Bible is particularly helpful: it identifies the amphiblēstron as a cast net, circular in form, with small weights around its perimeter, thrown so that it spreads out over the surface and encloses fish beneath it.
That is remarkably close to what we call a modern cast net.
A modern cast net is generally:
- circular;
- weighted around its circumference;
- gathered/folded in the fisherman’s hands;
- thrown outward;
- spread into a roughly circular shape;
- allowed to sink around the fish;
- then retrieved by a line attached to the net.
The ancient ἀμφίβληστρον appears to have operated on essentially this same principle.
So if you picture Simon standing on the shore, gathering a circular weighted net and throwing it outward so that it spreads across the water, that is much closer to Mark’s Greek than picturing him throwing a long seine net into the lake.
3. A seine is a different type of net
This distinction is particularly important for our discussion of the fishermen’s physical activity. The Greek word σαγήνη (sagēnē) refers to a drag net/seine. The Encyclopedia of the Bible describes this as a very different operation: a long net is taken around a section of water, often by boat, and the ends are subsequently hauled in. It compares this with the modern seine net.
So we have roughly:
| Greek | Type of net | Basic operation |
|---|---|---|
| ἀμφίβληστρον | Cast net | One person throws it outward over fish |
| σαγήνη | Seine/drag net | Net encloses an area and is hauled in |
| δίκτυον | General term | Fishing net of various kinds |
This distinction is also reflected in Greek lexicography. Thayer’s/Abbott-Smith’s lexical tradition specifically identifies ἀμφίβληστρον as a casting-net and σαγήνη as a drag/seine net, while δίκτυον is the broader term.
4. This is significant for the question about physical strength
This actually changes the age/strength question we were discussing. If Mark 1:16 were describing Simon and Andrew hauling a large seine, we could potentially argue that they were engaged in a particularly strenuous operation requiring several workers.
But that’s not what Mark says.
He says they were ἀμφιβάλλοντας ἀμφίβληστρον—casting a casting net. The NET Bible’s study note accordingly describes the net as circular with heavy weights around its perimeter and explicitly says the fishing was labor-intensive.
A cast net certainly requires strength and skill, particularly to throw it properly, but it is fundamentally a one-person casting operation, unlike hauling a large seine. That makes Mark’s contrast with James and John potentially more interesting.
5. Compare Mark 1:16 with 1:19
Mark gives us:
Simon & Andrew
casting (ἀμφιβάλλοντας)
ἀμφίβληστρον
into the sea
James & John
καταρτίζοντας
τὰ δίκτυα
mending/preparing the nets
Notice something important:
Mark does not use ἀμφίβληστρον for James and John’s nets.
He uses the much more general δίκτυα (diktya)—“nets.” The same word can refer to nets generally and does not identify the particular type. Lexicons explicitly characterize δίκτυον as the generic term for fishing nets, while amphiblēstron is the more specific casting net.
Therefore, we should not assume that James and John were mending the same type of net that Simon and Andrew were casting.
That’s an important qualification to our earlier discussion.
6. Could James and John have been mending large nets used from the boat?
Possibly. Mark doesn’t tell us what kind of nets they were repairing.
And there is a contextual reason to consider this. James and John are explicitly “in the boat”, whereas Mark depicts Simon and Andrew actively casting their amphiblēstron. James and John could therefore have been dealing with other fishing gear belonging to Zebedee’s operation. Mark’s mention of “hired men” also indicates that this was a larger organized fishing enterprise rather than two men operating a single cast net.
But we should resist going farther than the evidence allows. δίκτυον does not tell us that their nets were seine nets. It simply doesn’t identify the particular type.
7. Matthew confirms the cast-net terminology
This is especially useful because Matthew independently preserves the same detail. Matthew 4:18 says Simon and Andrew were:
βάλλοντας ἀμφίβληστρον εἰς τὴν θάλασσαν
—that is, “casting a net into the sea.”
Matthew therefore uses the same specific noun ἀμφίβληστρον that Mark uses. So this is not simply an English translator’s decision. Both Synoptic accounts explicitly identify Simon and Andrew’s net with the Greek term for a casting net.
Bottom line
Yes—the Greek strongly favors a cast net, not a seine, in Mark 1:16.
More precisely:
- “casting” = ἀμφιβάλλοντας, from amphiballō, “to throw/cast around.”
- “a net” = ἀμφίβληστρον, a specific type of casting net.
- The modern cast net is a very good functional analogy: a circular, weighted net thrown by hand over fish.
- A seine/drag net is a different type of net, associated with σαγήνη, and Mark does not use that word in 1:16.
- Mark uses the generic δίκτυα for James and John’s nets in 1:19, so we cannot determine from the Greek what type of nets they were mending.
And this has an important implication for your previous question: Mark’s contrast is not necessarily “strong men hauling a heavy seine versus younger men mending it.” Simon and Andrew were throwing a one-person cast net, while James and John were performing maintenance on unspecified nets in their boat. That makes the age inference from the two activities weaker than it initially appears.
However, the fact that Mark specifically chose ἀμφίβληστρον for Simon and Andrew gives us a much better basis for reconstructing exactly what Simon and Andrew were physically doing when Jesus encountered them.
