1 Corinthians 11:24-26 (King James Version)
24.
And when he had given thanks, he brake it, and said, Take, eat: this is
my body, which is broken for you: this do in remembrance of me.
25.
After the same manner also he took the cup, when he had supped, saying,
this cup is the new testament in my blood: this do ye, as oft as ye
drink it, in remembrance of me.
26. For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
