John 13:23-27

King James Version

²³ Now there was leaning on Jesus' bosom one of his disciples, whom Jesus loved.

²⁴ Simon Peter therefore beckoned to him, that he should ask who it should be of whom he spake.

²⁵ He then lying on Jesus' breast saith unto him, Lord, who is it?

²⁶ 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.

²⁷ And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.
