Matthew 26:20-29 ESV

When it was evening, he reclined at table with the twelve. And as they were eating, he said, “Truly, I say to you, one of you will betray me.” And they were very sorrowful and began to say to him one after another, “Is it I, Lord?” He answered, “He who has dipped his hand in the dish with me will betray me. The Son of Man goes as it is written of him, but woe to that man by whom the Son of Man is betrayed! It would have been better for that man if he had not been born.” Judas, who would betray him, answered, “Is it I, Rabbi?” He said to him, “You have said so.” Now as they were eating, Jesus took bread, and after blessing it broke it and gave it to the disciples, and said, “Take, eat; this is my body.” And he took a cup, and when he had given thanks he gave it to them, saying, “Drink of it, all of you, for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. I tell you I will not drink again of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom.”

1 Corinthians 11:23-26 ESV

For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, “This is my body, which is for you. Do this in remembrance of me.” In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” [26] For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.

The last supper is very much biblical
