Commandment to "love one another" and predicts Peter's denial of knowing him during his upcoming crucifixion. The discourse starts after the literal cleansing (washing of feet) and the figurative cleansing of the community of disciples via the departure of Judas. The discourse may be separated into four components: First discourse: 14:1–31, The theme of this part is departure and return; peace and joy, and is similar to the third discourse.

Yet he assures them that he will
