Mark 14:18

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).

Taken from John Gill's Exposition of the Bible

16 The disciples left, went to the city, and found everything just as Jesus had told them; and they prepared the Passover meal.

17 When it was evening, Jesus came with the twelve disciples.

18 While they were at the table eating, Jesus said, "I tell you that one of you will betray me - one who is eating with me."

19 The disciples were upset and began to ask him, one after the other, "Surely you don't mean me, do you?"

20 Jesus answered, "It will be one of you twelve, one who dips his bread in the dish with me.
