John 13
from this world Jesus’ work continues; His coming suffering and death is not the end, but the beginning. Although He is troubled by His coming death (12:27), He wants His disciples to have confidence in their knowledge that His death does not mark the end of His ministry.
13:6 Lord The Greek term used here, kyrios, means “ruler” or “master.” In the Septuagint (the Greek version of the Hebrew Scriptures, commonly used by early Christians), kyrios is used in place of the divine name, Yahweh.
If Peter is using kyrios in the sense of the divine name, then he is referring to Jesus as God. This seems to fit Jesus’ “I am” remark in v. 13.
13:8 To have no share with Jesus means that one does not belong to him. Here the footwashing symbolizes the washing necessary for the forgiveness of sins, in anticipation of Jesus’ death for his people, by which sins are washed away.
13:12–14. Disciples normally served their teachers, after the model of Elisha serving Elijah and Joshua serving Moses.
13:13 Teacher Jesus leads by example; by affirming this title here, He instructs the disciples to follow His example as they have already committed to doing. He reminds them that even in difficult times or in situations they consider beneath them (see note on v. 5), they must follow Him. See note on 1:38.
I am Jesus is likely evoking God’s chosen way of identifying Himself in the OT—saying that He is Yahweh, the God of Israel and ruler of the universe. This parallels what John says about Jesus in 1:1–4 and what Jesus knows of His own identity, revealed in v. 3. See note on 4:26.
13:15. Disciples were to learn especially by imitating their teachers.
13:16–17. Some slaves were prominent when compared with free peasants, but any authority slaves exercised was derived from their masters, and slaves were always subordinate to their masters. An agent was always subordinate to his sender, his authority limited to the extent of his authorization.
13:18 whom I have chosen Jesus is referencing all of His disciples who are present, but not Judas.
13:21 troubled in spirit Jesus feels the weight of His imminent suffering and death.
Disputes and arguments weren’t allowed at meals. This means that when Jesus brings up a betrayer being among them, He was breaking social norms, making this statement all the more surprising. Conversations proceeded in a manner that had to do with social rank, which is likely why Peter asks the disciple “whom Jesus loved” to ask Jesus who He is talking about. They are following social customs, not being secretive.
13:33. Teachers sometimes called their disciples “children” (cf. 1 Jn 2:1), and disciples called teachers “my father.” Jewish literature also included “testaments” of dying or departing famous heroes of the past giving important teachings to their children, to be read by future generations. Because Jesus is leaving, it is natural for him to provide final instructions to his disciples, whether or not John consciously follows the testamentary form here.
13:38 the rooster will not crow. See also Matt. 26:34; Mark 14:30; Luke 22:34. In a number of manuscripts of Mark’s Gospel, though not all, Mark mentions the rooster crowing “twice” (Mark 14:30, 68, 72), but roosters could crow a number of times separated by a few minutes. Mark specifies the first two individual crowings (as evidently Jesus did), while Matthew, Luke, and John focus on the shameful fact of Peter’s denial. They therefore drop this detail and report Jesus as referring to the entire set of crowings as the time the rooster crows.
