Mark 14:22-25

And while eating with them, Jesus took bread. And blessing it, he broke it and gave it to them, and he said: "Take. This is my body." And having taken the chalice, giving thanks, he gave it to them. And they all drank from it. And he said to them: "This is my blood of the new covenant, which shall be shed for many. Amen I say to you, that I will no longer drink from this fruit of the vine, until that day when I will drink it new in the kingdom of God."
