John 13:1-2; John 13:29

1 It was just before the Passover Festival. Jesus knew that the hour had come for him to leave this world and go to the Father. Having loved his own who were in the world, he loved them to the end. 2 The evening meal was in progress, and the devil had already prompted Judas, the son of Simon Iscariot, to betray Jesus.
29 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.
