John 17
17:2 The Father’s granting of authority over all flesh to Jesus (cf. 5:27) marks the start of a new era (cf. Isa. 9:6–7; Dan. 7:13–14; see also Matt. 11:27; 28:18). “All flesh” means the whole human race.
17:5 Jesus again claims that he existed before the world existed (or “before the world was”; cf. 1:1, 14; 3:13; 6:62; 8:58; 16:28; 17:24).
17:6 Jesus’ revelation of God’s name entails making known the Father in his whole person, both his works and words (cf. 1:18; 8:19, 27; 10:38; 12:45; 14:9–11).
men whom you gave me Refers to those who came to Jesus to hear His message of salvation.
17:12 I kept them in your name Indicates that Jesus kept His disciples secure in their faith through divine authority and power.
Here Jesus might allude to Psalm 41:9, which he cited in John 13:18. Jewish teaching recognized that God dealt more severely with apostates than with those who were born pagans, because apostates had known the truth but turned away from it.
