From Matthew 21:

“Tell us then, what is your opinion?” [the Pharisees and Herodians asked Jesus]. “Is it right to pay taxes to Caesar or not?”
But Jesus, knowing their evil intent, said, “You hypocrites, why are you trying to trap me? Show me the coin used for paying the tax.” They brought him a denarius, and he asked them, “Whose portrait is this? And whose inscription?”
“Caesar’s,” they replied. Then he said to them, “Give to Caesar what is Caesar’s, and to God what is God’s.”
When they heard this, they were amazed. So they left him and went away.
