Mark 14:16-19

16The disciples left, went into the city and found things just as Jesus had told them. So they prepared the Passover. 17When evening came, Jesus arrived with the Twelve.

18While they were reclining at the table eating, he said, “Truly I tell you, one of you will betray me—one who is eating with me.”

19They were saddened, and one by one they said to him, “Surely you don’t mean me?”
