Matthew 22:20-22

20 Then he said to them, "Whose head is this, and whose title?"
21 They answered, "The emperor's." Then he said to them, "Give therefore to the emperor the things that are the emperor's, and to God the things that are God's."
22 When they heard this, they were amazed; and they left him and went away.
