John 13:23-28

23Now there was leaning on Jesus’ bosom one of his disciples, whom Jesus loved. 24Simon Peter therefore beckoned to him, to ask who it should be of whom he spoke. 25He then lying on Jesus’ breast saith to him, Lord, who is it? 26Jesus 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.1 27And after the sop Satan entered into him. Then said Jesus to him, What thou doest, do quickly. 28Now no man at the table knew for what intent he spoke this to him.
