1 Corinthians 11:24-26

and when he had given thanks, he brake it, and said, This is my body, which is for you: this do in remembrance of me. In like manner also the cup, after supper, saying, This cup is the new covenant in my blood: this do, as often as ye drink it, in remembrance of me. For as often as ye eat this bread, and drink the cup, ye proclaim the Lord’s death till he come.
