      14. Then the Pharisees went out, and held a council against him, how they might destroy him--This is the first explicit mention of their murderous designs against our Lord. Luke (Lu 6:11) says, "they were filled with madness, and communed one with another what they might do to Jesus." But their doubt was not, whether to get rid of Him, but how to compass it. Mark (Mr 3:6), as usual, is more definite: "The Pharisees went forth, and straightway took counsel with the Herodians against Him, how they might destroy Him." These Herodians were supporters of Herod's dynasty, created by Cæsar--a political rather than religious party. The Pharisees regarded them as untrue to their religion and country. But here we see them combining together against Christ as a common enemy. So on a subsequent occasion (Mt 22:15, 16).
