Follow the Pharisaic law – Matthew 23:1-3 — 1 Then Jesus said to the crowds and to his disciples, 2 “The scribes and the Pharisees sit on Moses’s seat; 3 therefore, do whatever they teach you and follow it, but do not do as they do, for they do not practice what they teach.” NRSV
Reminder – The Pharisees’ insistence on the binding force of oral tradition (“the unwritten Torah”) remains a basic tenet of Jewish theological thought. When the Mishna (the first constituent part of the Talmud) was compiled about 200 ce, it incorporated the teachings of the Pharisees on Jewish law. – Britannica
