Mark saith, Mark 12:13, They send unto him certain of the Pharisees and of the Herodians, to catch him in his words. Luke saith, Luke 20:20, They watched him, and sent forth spies, which should feign themselves just men, that they might take hold of his words, that so they might deliver him unto the power and authority of the governor. His life was what they sought for. This they had no power allowed by the Romans to take away without the sentence of Pontius Pilate, the Roman governor. That they might have something to accuse him of before him, which he might condemn him for, they first take counsel. They saw he did nothing worthy of death; they therefore issue their counsels in a resolution to send some persons to discourse with him, under the pretence of conscientious, good men, to propound some questions to him, his answer to which might give them some opportunity to accuse him of blasphemy or sedition. The men they pitch upon were some of them Pharisees, some Herodians.
