Mark 14:19

16 His disciples went out, and came into the city, and found things as he had said to them, and they prepared the Passover.

17 When it was evening he came with the twelve.

18 As they sat and were eating, Jesus said, "Most assuredly I tell you, one of you will betray me -- he who eats with me."

19 They began to be sorrowful, and to ask him one by one, "Surely not I?" And another said, "Surely not I?"

20 He answered them, "It is one of the twelve, he who dips with me in the dish.

21 For the Son of Man goes, even as it is written about him, but woe to that man through whom the Son of Man is betrayed! It would be better for that man if he had not been born."

22 As they were eating, Jesus took bread, and when he had blessed, he broke it, and gave to them, and said, "Take, eat. This is my body."
