1 Corinthians 11:23-26

For I received from the Lord Himself that which I passed on to you [it was given to me personally], that the Lord Jesus on the night when He was treacherously delivered up and while His betrayal was in progress took bread, And when He had given thanks, He broke [it] and said, Take, eat. This is My body, which is broken for you. Do this to call Me [affectionately] to remembrance. Similarly when supper was ended, He took the cup also, saying, This cup is the new covenant [ratified and established] in My blood. Do this, as often as you drink [it], to call Me [affectionately] to remembrance. For every time you eat this bread and drink this cup, you are representing and signifying and proclaiming the fact of the Lord's death until He comes [again].
