John 13:25-29

He then lying on Jesus’ breast saith unto him, Lord, who is it?

Jesus answered, He it is, to whom I shall give a sop, when I have dipped it. And when he had dipped the sop, he gave it to Judas Iscariot, the son of Simon.

And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.

Now no man at the table knew for what intent he spake this unto him.

For some of them thought, because Judas had the bag, that Jesus had said unto him, Buy those things that we have need of against the feast; or, that he should give something to the poor.
