15 Then the Pharisees met together to plot how to trap Jesus into saying something for which he could be arrested. 16 They sent some of their disciples, along with the supporters of Herod, to meet with him. "Teacher," they said, "we know how honest you are. You teach the way of God truthfully. You are impartial and don't play favorites. 17 Now tell us what you think about this: Is it right to pay taxes to Caesar or not?" 18 But Jesus knew their evil motives. "You hypocrites!" he said. "Why are you trying to trap me? 19 Here, show me the coin used for the tax." When they handed him a Roman coin, 20 he asked, "Whose picture and title are stamped on it?" 21 "Caesar's," they replied. "Well, then," he said, "give to Caesar what belongs to Caesar, and give to God what belongs to God."

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.
