Pseudo-Jerome
Catena Aurea · Markusevangelium 14
And in the evening he cometh with the twelve. And as they sat and did eat, Jesus said, Verily I say unto you, One of you which eateth with me shall betray me. And they began to be sorrowful, and to say unto him one by one, Is it I? and another said, Is it I? And he answered and said unto them, It is one of the twelve, that dippeth with me in the dish. The Son of man indeed goeth, as it is written of him: but woe to that man by whom the Son of man is betrayed! good were it for that man if he had never been born.
Again, He says, One out of the twelve, as it were separate from them, for the wolf carries away from the flock the sheep which he has taken, and the sheep which quits the fold lies open to the bite of the wolf. But Judas does not withdraw his foot from his traitorous design though once and again pointed at, wherefore his punishment is foretold, that the death denounced upon him might correct him, whom shame could not overcome; wherefore it goes on: The Son of man indeed goeth, as it is written of him.
