John 13:21-30 - Jesus Predicts Judas' Betrayal
21 After Jesus said this, He felt disturbed in His spirit and declared, "Truly, truly, I tell you, one of you will turn me over [to the Jewish authorities]."
22 The disciples looked at one another, puzzled over who He was talking about. 23 One of Jesus' disciples, [the one] He loved [Note: Probably this was the apostle John] was reclining at the dinner table close to Jesus. 24 So, Simon Peter motioned [to John] and said, "Ask Jesus which one [of us] He is talking about." 25 So, John leaned over close to Jesus and asked Him, "Lord, who is it?"
26 Jesus answered, "It is the person to whom I give a piece of bread after dipping it [in the sauce bowl]." So, when He had dipped the piece of bread, He took it [out] and gave it to Judas, the son of Simon Iscariot. 27 Then after [he ate] the piece of bread, Satan entered Judas' heart. So, Jesus said to him, "Do what you are going to do, and do it quickly."
28 Now, no one at the table knew why He had said this to him. 29 For some of them thought, since Judas was in charge of the [money] bag, that Jesus was telling him, "Buy whatever we need for the [Passover] meal," or that he was [being told] to give [money] to poor people [from it]. 30 So, after eating the piece of bread, Judas went out immediately. And it was nighttime.
