Now, as they were eating, Jesus took bread, and blessed, and broke it, and gave it to the disciples and said, "Take, eat; this is my body." And he took a cup, and when he had given thanks he gave it to them saying, "Drink of it, all of you; for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. I tell you I shall not drink again of this fruit of the vine until that day when I drink it new with you in my Father's kingdom." And when they had sung a hymn, they went out to the Mount of Olives.

St. Matthew 26:26-30
