Jesus, knowing that His hour had come washes His disciple feet. He instructs His disciples to imitate Him and serve one another. At the last supper, Jesus gives the sop to Judas Iscariot after He had dipped it. Judas leaves immediately after Satan enters him.
In the act of servitude, Jesus commands His disciples to love one another and that this is how the world would know that they belong to Him. Peter is adamant that he will lay down his life for Jesus. Jesus tells him that before the cock crows, Peter will deny him 3 times.
