Mark 12:14-15

So they approached him and said, “Teacher, we know that you’re an honest man of integrity and you teach us the truth of God’s ways. We can clearly see that you’re not one who speaks only to win the people’s favor, because you speak the truth without regard to the consequences. So tell us, then, what you think. Is it proper for us to pay taxes to Caesar or not?” Jesus saw through their hypocrisy and said to them, “Why are you testing me? Show me one of the Roman coins.”
