1 Corinthians 11:25

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

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.
