13 Then they sent to him certain of the Pharisees and the Herodians, so that they might make use of his words to take him by a trick. 14 And when they had come, they said to him, Master, we are certain that you are true, and have no fear of anyone: you have no respect for a man's position, but you are teaching the true way of God: Is it right to give taxes to Caesar or not?
Matthew Henry's Commentary on Mark 12:13-14
Commentary on Mark 12:13-17
(Read Mark 12:13-17)
The enemies of Christ would be thought desirous to know their duty, when really they hoped that which soever side he took of the question, they might find occasion to accuse him. Nothing is more likely to insnare the followers of Christ, than bringing them to meddle with disputes about worldly politics. Jesus avoided the snare, by referring to the submission they had already made as a nation; and all that heard him, marvelled at the great wisdom of his answer. Many will praise the words of a sermon, who will not be commanded by the doctrines of it.
