Jerome, on Matt 22:15

“Then the Pharisees going, consulted among themselves how to insnare him in his speech.”

“Wisdom does ever wisely, and so the tempters are best confuted out of their own words; therefore it follows, Shew me the tribute money; and they brought unto Him a denarius. This was a coin reckoned equivalent to ten sesterces, and bore the image of Cæsar. Let those who think that the Saviour asks because He is ignorant, learn from the present place that it is not so, for at all events Jesus must have known whose image was on the coin. They say unto Him, Cæsar’s; not Augustus, but Tiberius, under whom also the Lord suffered. All the Roman Emperors were called Cæsar, from Caius Cæsar who first seized the chief power. Render therefore unto Cæsar the things which are Cæsar’s; i. e. the coin, tribute, or money.”
