20 And Jesus said to them, "Whose likeness and inscription is this?" 21 They said, "Caesar's." Then he said to them, "Therefore render to Caesar the things that are Caesar's, and to God the things that are God's." 22 When they heard it, they marveled. And they left him and went away.

Commentary on Matthew 22:15-22
(Read Matthew 22:15-22)
The Pharisees sent their disciples with the Herodians, a party among the Jews, who were for full subjection to the Roman emperor. Though opposed to each other, they joined against Christ. What they said of Christ was right; whether they knew it or not, blessed be God we know it. Jesus Christ was a faithful Teacher, and a bold reprover. Christ saw their wickedness. Whatever mask the hypocrite puts on, our Lord Jesus sees through it. Christ did not interpose as a judge in matters of this nature, for his kingdom is not of this world, but he enjoins peaceable subjection to the powers that be. His adversaries were reproved, and his disciples were taught that the Christian religion is no enemy to civil government. Christ is, and will be, the wonder, not only of his friends, but of his enemies. They admire his wisdom, but will not be guided by it; his power, but will not submit to it.
