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 betrayed him, said, "Is it I, Master?" He said to him, "You have said so." Matthew 26:20-25
Now as they were eating, Jesus took bread and blessed and broke it and gave it to the disciples and said, "Take, eat; this is my body."
And he took a chalice, 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." Matthew 26:26-28
