ISB ~ 2 Peter 2 v4

the angels:Probably a reference to Jewish traditions I surrounding Gen 6:1-4, according to which the “sons of God” are rebel angels, called the Watchers, who had sexual relations with women and begot a generation of giants (1 Enoch 6-21; Jubilees 5, 1-11). See note on Jude 6.

into hell:Literally, “into Tartarus”, the lower region of the underworld, where, according to Greek mythology, the wicked are imprisoned. Scripture elsewhere refers to the netherworld as Sheol, Hades, the Abyss, or the Pit.

• The scenario described by Peter recalls one of the visions of Isaiah, in which the ungodly of heaven (angels) and earth (kings) are hurled as prisoners into a pit to await their final punishment (Is 24:21-22).
