“They say unto him, Caesar's. Then saith he unto them, Render therefore unto Caesar the things which are Caesar's; and unto God the things that are God's.”
King James Version (KJV)
22:21 They say to him, Cesar's - Plainly acknowledging, by their having received his coin, that they were under his government. And indeed this is a standing rule. The current coin of every nation shows who is the supreme governor of it. Render therefore, ye Pharisees, to Cesar the things which ye yourselves acknowledge to be Cesar's: and, ye Herodians, while ye are zealous for Cesar, see that ye render to God the things that are God's.
Mt 22:21 Render therefore unto Caesar. The use of Caesar's coin as the current money was an acknowledgment of Caesar. Let them return his coin when demanded. Unto God the things that are God's. Obedience in moral and spiritual things. Faith, love, obedience and liberal giving for God's work. We are to obey the human government over us, and to obey God. When the first requires us to disobey God, we are to obey him, whatever may be the peril. See Ac 5:29.
