Simon Peter makes a sign therefore to him to ask who it might be of whom he spoke.
But he, leaning on the breast of Jesus, says to him, Lord, who is it?
Jesus answers, He it is to whom I, after I have dipped the morsel, give it. And having dipped the morsel, he gives it to Judas [son] of Simon, Iscariote.
And, after the morsel, then entered Satan into him. Jesus therefore says to him, What thou doest, do quickly.
But none of those at table knew why he said this to him;
for some supposed, because Judas had the bag, that Jesus was saying to him, Buy the things of which we have need for the feast; or that he should give something to the poor.
Having therefore received the morsel, he went out immediately; and it was night.
