John 13:27-30 NIV
As soon as Judas took the bread, Satan entered into him.
So Jesus told him, “What you are about to do, do quickly.” But no one at the meal understood why Jesus said this to him. Since Judas had charge of the money, some thought Jesus was telling him to buy what was needed for the festival, or to give something to the poor. As soon as Judas had taken the bread, he went out. And it was night.
