Luke 22:19,20 (NIV)

¹⁹And he took bread, gave thanks and broke it, and gave it to them, saying, "This is my body given for you; do this in remembrance of me." ²⁰In the same way, after the supper he took the cup, saying, "This cup is the new covenant in my blood, which is poured out for you.

1 Corinthians 10:16 (NIV)

¹⁶Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ?

1 Corinthians 11:23-26 (NIV)

²³For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, ²⁴and when he had given thanks, he broke it and said, "This is my body, which is for you; do this in remembrance of me." ²⁵In the same way, after supper he took the cup, saying, "This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me." ²⁶For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes.
