"[...] When Jesus had thus spoken, he was troubled in spirit, and testified, "Truly, truly, I say to you, one of you will betray me." [...]
One of his disciples, whom Jesus loved, was lying close to the breast of Jesus [...] said to him,
"Lord, who is it?"
Jesus answered,
"It is he to whom I shall give this morsel when I have dipped it." So when he had dipped the morsel, he gave it to Judas [...]
So, after receiving the morsel, he immediately went out; and it was night. " (John 13, 21-30).
