14 And they come and say to him, Teacher, we know that thou art true, and carest not for any one; for thou regardest not men's person, but teachest the way of God with truth: Is it lawful to give tribute to Caesar or not? 15 Should we give, or should we not give? But he knowing their hypocrisy said unto them, Why tempt ye me? Bring me a denarius that I may see [it]. 16 And they brought [it]. And he says to them, Whose [is] this image and superscription? And they said to him, Caesar's. 17 And Jesus answering said to them, Pay what is Caesar's to Caesar, and what is God's to God. And they wondered 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.
