For I received from the Lord that which I also delivered to you, that the Lord Jesus the same night in which He was betrayed took bread; And when He had given thanks, He broke it, and said, "Take, eat This is My body, which is broken for you; this do in remembrance of Me." in the same like manner He took the cup, after supper, saying, "This cup is the new covenant in my blood. This * do, as often as you drink* it in remembrance of Me." For as often as you eat * this bread and drink the cup, you show the Lord's death until * He comes.
1 Corinthians 11:23-26
