(18) As they sat.--Better, as they reclined.

Verse 18. - Verily I say unto you, One of you shall betray me, even he that eateth with me (ὁ ἐσθίων μετ ἐμοῦ). Much had doubtless happened before our Lord said this; but St. Mark only records the important circumstances. These words of our Lord were uttered with great solemnity. The presence of the traitor was a burden upon his spirit, and cast a gloom over this usually joyous festival. A question here arises whether Judas remained to partake of the Holy Communion when our Lord instituted it. The greater number of the Fathers, and amongst them Origen, St. Cyril, St. Chrysostom, St. Augustine, and Bede, consider that he was present; and Dionysius says that our Lord's words to him, "That thou doest, do quickly," were intended to separate him from the rest of the twelve as one who had partaken unworthily; and that then it was that Satan entered into him, and impelled him onwards to this terrible sin.

14:12-21 Nothing could be less the result of human foresight than the events here related. But our Lord knows all things about us before they come to pass. If we admit him, he will dwell in our hearts. The Son of man goes, as it is written of him, as a lamb to the slaughter; but woe to that man by whom he is betrayed! God's permitting the sins of men, and bringing glory to himself out of them, does not oblige them to sin; nor will this be any excuse for their guilt, or lessen their punishment.And as they sat and did eat,.... Or "as they lay along"; for such was their posture at the eating of the passover; See Gill on Matthew 26:20,

Jesus said, verily I say unto you, one of you which eateth with me shall betray me; See Gill on Matthew 26:21.
