During supper — the devil having already put it into the heart of Judas Iscariot, son of Simon, to betray him —
In context
1It was just before the festival of the Passover. Jesus knew that his hour had come to pass from this world to the Father. He had loved his own who were in the world, and he loved them to the end. 2During supper — the devil having already put it into the heart of Judas Iscariot, son of Simon, to betray him — 3Jesus, knowing that the Father had put everything into his hands, and that he had come from God and was going back to God, 4got up from the meal, laid aside his outer clothing, took a towel and tied it around his waist.
