John 13:3

Jesus, knowing that the Father had given all things into his hands, and that he came forth from God, and goeth unto God, riseth from supper, and layeth aside his garments; and he took a towel and girded himself.

All things into his hands ... The Lord was about to give an object lesson in humility, but it was given in full consciousness of his power and Godhead. John was more perceptive in his association of the Godhead of Jesus with the darkest hours of the Lord's humiliation. Matthew mentioned "all authority" as belonging to Christ but associated it with the Great Commission (Matthew 28:18-20). Of course, both Gospels are correct.

Riseth from supper ... If this had been the passover, Jesus could not have eaten it reclining (Exodus 12:11). Jesus rose up from the reclining position customary at meals in those days, laid aside his outer robe, or garment, and girded himself with a towel, the clothing suggestive of a slave.
