1 Corinthians 11:25-26, 33
1 Corinthians 11:25-26 NASB1995
In the same way He took the cup also after supper, saying, “This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.” For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes.
1 Corinthians 11:33 NASB1995
So then, my brethren, when you come together to eat, wait for one another.
