John 13 is the thirteenth chapter of the Gospel of John in the New Testament of the Christian Bible. It begins John's record of the events on the last night before the crucifixion of Jesus Christ, emphasising Jesus' love for His disciples, demonstrated in the service of washing their feet, and His commandment that they love one another in the same way. The book containing this chapter is anonymous, but early Christian tradition uniformly affirmed that John composed this Gospel.
