18 I’m not talking about all of you—I know those I have chosen. But this is to fulfill Scripture: ‘The one who shares my food has turned against me.’13:18. Quoting Psalms 41:9. 19 I’m telling you this now, before it happens, so when it does happen you will be convinced that I am who I am. 20 I tell you the truth, whoever welcomes anyone I send welcomes me; and whoever welcomes me, welcomes the one who sent me."
21 After he had said this, Jesus was deeply troubled, and declared: "I tell you the truth, one of you is going to betray me." 22 The disciples looked at each other, wondering which of them Jesus was talking about. 23 The disciple whom Jesus loved13:23. Usually understood as John referring to himself. (See also 20:2, 21:7, 21:20.) was sitting next to Jesus at the table, leaning close to him. 24 Simon Peter motioned to him to ask Jesus which one he was talking about. 25 So he leaned over to Jesus and asked, "Lord, who is it?"
26 Jesus replied, "It’s the one to whom I will give a piece of bread after I have dipped it." 27 After dipping the piece of bread, he gave it to Judas, son of Simon Iscariot. Once Judas had taken the bread, Satan entered him. "What you’re going to do, do it quickly," Jesus told him.
28 No one at the table understood what Jesus meant by this. 29 Since Judas was in charge of the money, some of them thought that Jesus was telling him to go and buy what was needed for the Passover festival, or to donate something to the poor. 30 Judas left immediately after he’d taken the piece of bread, and went out into the night.
