1 Corinthians 11:23-25

23For I received from the Lord Himself that [instruction] which I passed on to you, that the Lord Jesus on the night in which He was betrayed took bread;

24and when He had given thanks, He broke it and said, “This is (represents) My body, which is [offered as a sacrifice] for you. Do this in [affectionate] remembrance of Me.”

25In the same way, after supper He took the cup, saying, “This cup is the new covenant [ratified and established] in My blood; do this, as often as you drink it, in [affectionate] remembrance of Me.”
