John 13:21-30 - Jesus Predicts Judas' Betrayal
21 After Jesus had said this he was greatly moved and said solemnly, "I tell you, it is one of you that will betray me!"
22 The disciples looked at one another in doubt as to which of them he meant. 23 Next to Jesus, at his right at the table, was one of his disciples whom Jesus especially loved. 24 So Simon Peter nodded to him and said to him, "Tell us whom he means." 25 He leaned back from where he lay, on Jesus' breast, and said to him, "Master, who is it?"
26 Jesus answered, "It is the one to whom I am going to give this piece of bread when I have dipped it in the dish." So he dipped the piece of bread and took it and gave it to Judas, Simon Iscariot's son. 27 After he took the bread, Satan took possession of him. Then Jesus said to him, "Be quick about your business."
28 But no one else at the table knew what he meant by telling him this, 29 for some of them thought that as Judas had the purse Jesus meant to say to him, "Buy what we need for the festival," or to have him give something to the poor. 30 So immediately after taking the piece of bread he went out. It was then night.
