John 13:2, 10-11, 18-19, 21-28

And during supper, the devil having already put into the heart of Judas Iscariot, Simon’s son, to betray him

Jesus saith to him, He that is bathed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all. For he knew him that should betray him; therefore said he, Ye are not all clean.

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. From henceforth I tell you before it come to pass, that, when it is come to pass, ye may believe that I am he.

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. The disciples looked one on another, doubting of whom he spake. There was at the table reclining in Jesus’ bosom one of his disciples, whom Jesus loved. Simon Peter therefore beckoneth to him, and saith unto him, Tell us who it is of whom he speaketh. He leaning back, as he was, on Jesus’ breast saith unto him, Lord, who is it? 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.
