John 13:21, 26, 30

After Jesus had said these things, He was troubled in spirit, and testified and said, “I assure you and most solemnly say to you, one of you will betray Me and hand Me over.”

Jesus answered, “It is the one to whom I am going to give this piece [of bread]after I have dipped it.” So when He had dipped the piece of bread [into the dish], He gave it to Judas, son of Simon Iscariot.

After taking the piece of bread, he went out immediately; and it was night.
