John 13:18-30 - The Announcement Of Jesus' Betrayal
18 I am not speaking about all of you. I know whom I have chosen; but this is in fulfillment of the words of Scripture--'He that is eating my bread has lifted his heel against me.'
19 For the future I shall tell you of things before they take place, so that, when they take place, you may believe that I am what I am. 20 In truth I tell you, he who receives any one that I send receives me; and he who receives me receives him who sent me."
21 After saying this, Jesus was much troubled, and said solemnly: "In truth I tell you that it is one of you who will betray me."
22 The disciples looked at one another, wondering whom he meant. 23 Next to Jesus, in the place on his right hand, was one of his disciples, whom he loved. 24 So Simon Peter made signs to that disciple, and whispered: "Tell me who it is that he means." 25 Being in this position, that disciple leant back on Jesus' shoulder, and asked him: "Who is it, Master?"
26 "It is the one," answered Jesus, "to whom I shall give a piece of bread after dipping it in the dish." And, when Jesus had dipped the bread, he took it and gave it to Judas, the son of Simon Iscariot; 27 And it was then, after he had received it, that Satan took possession of him. So Jesus said to him: "Do at once what you are going to do."
28 But no one at table understood why he said this to Judas. 29 Some thought that, as Judas kept the purse, Jesus meant that he was to buy some things needed for the Festival, or to give something to the poor. 30 After taking the piece of bread, Judas went out immediately; and it was night.
