John 13:27-29

After [Judas had taken] the piece of bread, Satan entered him. Then Jesus said to him, “What you are going to do, do quickly [without delay].” But no one reclining at the table knew why He said this to him. Some thought that, since Judas [as the treasurer of the group] had the money box, Jesus was telling him, “Buy what we need for the feast,” or that he was to give something to the poor.
