Two major events occur in this passage: 1) Satan put into the heart of Judas to betray Jesus and 2) Jesus washed the feet of the disciples. There is a third emphasis revealing His knowledge as God. He knew that His hour had come and where He came from and where He was going. He knew that Judas would be betraying Him and that the Father had given all things into His hands (13:3). In the washing of the disciples feet, He taught them two great lessons: 1) The importance of serving one another and 2) that true happiness comes from humble service.
