Having Loved His Own the foot-washing and the beginning of the Farewell Discourse
John 13 opens the "Book of Glory" (chapters 13–21). On the night of his betrayal, the Lord who holds all things in his hands takes a towel and washes his disciples' feet, sends the betrayer out into the night, and gives the new commandment that will mark his people: "love one another, as I have loved you."
Overview of John 13
13:1–17 is the foot-washing. Knowing that his hour had come and that the Father had given all things into his hands, Jesus rises from supper, girds himself with a towel, and washes his disciples' feet — an enacted parable of the cleansing only his death can give ("unless I wash you, you have no part with me") and an example of humble, serving love. 13:18–30 turns to the betrayer: Jesus, troubled in spirit, identifies Judas by the morsel, Satan enters him, and he goes out — "and it was night."
13:31–38 begins the Farewell Discourse proper. With Judas gone, Jesus announces, "Now is the Son of Man glorified," gives the "new commandment" to love one another as the badge of discipleship, and foretells Peter's threefold denial before the rooster crows — even as he promises that Peter will follow him afterward.
