John 13:26-28 World English Bible (WEB)
26 Jesus therefore answered, “It is he to whom I will give this piece of bread when I have dipped it.” So when he had dipped the piece of bread, he gave it to Judas, the son of Simon Iscariot. 27 After the piece of bread, then Satan entered into him.
Then Jesus said to him, “What you do, do quickly.”
28 Now no man at the table knew why he said this to him.
