John 13:18-28

18 I speak not of you all: I know whom I have chosen: but that the scripture may be fulfilled: He that eateth my bread lifted up his heel against me.
19 From henceforth I tell you before it come to pass, that, when it is come to pass, ye may believe that I am [he].
20 Verily, verily, I say unto you, he that receiveth whomsoever I send receiveth me; and he that receiveth me receiveth him that sent me.
21 When Jesus had thus said, he was troubled in the spirit, and testified, and said, Verily, verily, I say unto you, that one of you shall betray me.
22 The disciples looked one on another, doubting of whom he spake.
23 There was at the table reclining in Jesus' bosom one of his disciples, whom Jesus loved.
24 Simon Peter therefore beckoneth to him, and saith unto him, Tell [us] who it is of whom he speaketh.
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.
