14 When they had come, they said to Him, "Teacher, we know that You are true, and care about no one; for You do not regard the person of men, but teach the way of God in truth. Is it lawful to pay taxes to Caesar, or not? 15 Shall we pay, or shall we not pay?" But He, knowing their hypocrisy, said to them, "Why do you test Me? Bring Me a denarius that I may see it." 16 So they brought it. And He said to them, "Whose image and inscription is this?" They said to Him, "Caesar's." 17 And Jesus answered and said to them, "Render to Caesar the things that are Caesar's, and to God the things that are God's." And they marveled 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.
