Charles Ellicott Commentary Mark 14:21

"For the Son of man goeth, even as it is written of him: but woe unto that man through whom the Son of man is betrayed! good were it for that man if he had not been born." — Mark 14:21 (ASV)

Good were it for that man.—Saint Mark, it will be noted, omits the fact recorded by Saint Matthew, that the last Is it I? was uttered by the Traitor.
