John Chrysostom — as excerpted in the Catena Aurea on Mark 14:10-11

“(ubi sup.) Oh! the madness, yea, the avarice of the traitor, for his covetousness brought forth all the evil. For covetousness retains the souls which it has taken, and confines them in every way when it has bound them, and makes them forget all things, maddening their minds. Judas, taken captive by this madness of avarice, forgets the conversation, the table of Christ, his own discipleship, Christ’s warnings and persuasion. For there follows, And he sought how he might conveniently betray him.”
