John Chrysostom — as excerpted in the Catena Aurea on Luke 22:3-6

“(ut sup.) By covetousness then Judas became what he was, for it follows, And they covenanted to give him money. Such are the evil passions which covetousness engenders, it makes men irreligious, and compels them to lose all knowledge of God, though they have received a thousand benefits from Him, nay, even to injure Him, as it follows, And he contracted with them.”
