During the Passover meal, Jesus prophesied that one disciple would betray him, and he gave them the bread and wine which he said represented his body and blood which would be sacrificed.

Mark 14:18-26

18 As they were all sitting there and eating, Jesus said, “Listen carefully to this: One of you will enable my enemies to seize me. Specifically, it is one of you who will do this in spite of the fact that he is eating with me right now!” 19 The disciples became very sad and they said to him one by one, “Surely ◄it is not I!/I am not the one, am I?► [RHQ]” 20 Then he said to them, “It is one of you twelve disciples, the one who is dipping bread into the sauce in the dish along with me. 21 It is certain that I, the one who came from heaven, will die, because that is what has been {what the prophets have} written about me. But there will be terrible punishment for the man by whom I will be betrayed {who will ◄betray me/help my enemies to seize me►}! In fact, it would be better for that man if he had never been born!”

22 While they were eating, he took a flat loaf of bread and thanked God for it. Then he broke it into pieces and gave it to them and said to them, “This bread represents [MET] my body. Take it and eat it.” 23 Afterwards, he took a cup that contained wine and thanked God for it. Then he gave it to them, and then, as they all drank from it, 24 he said to them, “This wine represents [MET] my blood, which is about to be shed {which is about to flow from my body} when my enemies kill me. With this blood I will sign the agreement that God has made to forgive the sins of many people. 25 I want you to know this: I will not drink any more wine in this way until the time when I drink it with a new meaning when I begin to rule as a king.” 26 After they sang a hymn, they went out toward Olive Tree Hill.
