13 Then they sent to him some Pharisees and some Herodians to trap him in what he said. 14 And they came and said to him, "Teacher, we know that you are sincere, and show deference to no one; for you do not regard people with partiality, but teach the way of God in accordance with truth. Is it lawful to pay taxes to the emperor, or not? 15 Should we pay them, or should we not?" But knowing their hypocrisy, he said to them, "Why are you putting me to the test? Bring me a denarius and let me see it." 16 And they brought one. Then he said to them, "Whose head is this, and whose title?" They answered, "The emperor's." 17 Jesus said to them, "Give to the emperor the things that are the emperor's, and to God the things that are God's." And they were utterly amazed at him.

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.
