John 13:27 ASV

²⁵  He leaning back, as he was, on Jesus' breast saith unto him, Lord, who is it?

²⁶  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.

²⁷  And after the sop, then entered Satan into him. Jesus therefore saith unto him, What thou doest, do quickly.

²⁸  Now no man at the table knew for what intent he spake this unto him.

²⁹  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.
