14 And they came and said to him, "Teacher, we know that you are true, and care for no man; for you do not regard the position of men, but truly teach the way of God. Is it lawful to pay taxes to Caesar, or not? 15 Should we pay them, or should we not?" But knowing their hypocrisy, he said to them, "Why put me to the test? Bring me a coin, and let me look at it." 16 And they brought one. And he said to them, "Whose likeness and inscription is this?" They said to him, "Caesar's." 17 Jesus said to them, "Render to Caesar the things that are Caesar's, and to God the things that are God's." And they were 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.
