John 13:26-30

Jesus therefore answereth, He it is, for whom I shall dip the sop, and give it him. So when he had dipped the sop, he taketh and giveth it to Judas, the son of Simon Iscariot. And after the sop, then entered Satan into him. Jesus therefore saith unto him, What thou doest, do quickly. Now no man at the table knew for what intent he spake this unto him. For some thought, because Judas had the bag, that Jesus said unto him, Buy what things we have need of for the feast; or, that he should give something to the poor. He then having received the sop went out straightway: and it was night.
