None of the others at the table knew what Jesus meant.
Since Judas was their treasurer, some thought Jesus was telling him to go and pay for the food or to give some money to the poor.
So Judas left at once, going out into the night.
As soon as Judas left the room, Jesus said, "The time has come for me, the Son of Man, to enter into my glory, and God will receive glory because of all that happens to me.
And God will bring me into my glory very soon.
