Luke 20: 21-26
So the spies questioned him: “Teacher, we know that you speak and teach what is right, and that you do not show partiality but teach the way of God in accordance with the truth. [22] Is it right for us to pay taxes to Caesar or not?” [23] He saw through their duplicity and said to them, [24] “Show me a denarius. Whose image and inscription are on it?” “Caesar's,” they replied. [25] He said to them, “Then give back to Caesar what is Caesar's, and to God what is God's.” [26] They were unable to trap him in what he had said there in public. And astonished by his answer, they became silent.

I remember this story from reading it when I was young, and marveled then at Jesus' wisdom. The scribes and chief priests thought they had finally cornered Jesus with a question that Jesus wouldn't be able to answer, and He did and showed wisdom.
The point of this story is something we can still learn from, as we often deal with a government we don't agree with. But the wisdom that Jesus showed in answering this question was truly amazing!
