The chief priests and Pharisees were a great part of that great council amongst the Jews, which went under the name of the sanhedrim; and this (probably) was the council they gathered; for, 1 Thessalonians 11:49, we read, that Caiaphas, the high priest, the standing president of that court, was amongst them. The miracles wrought by Christ were the things that disturbed them, and they reflect upon themselves for conniving so long at him: what they should have improved (viz. the miracles which he wrought) to have begot or increased faith in them, they mention and misimprove to their destruction.
