Expositor's Bible Commentary Commentary Jude 1:6

"And angels that kept not their own principality, but left their proper habitation, he hath kept in everlasting bonds under darkness unto the judgment of the great day." — Jude 1:6 (ASV)

The second example is of the fallen angels. The most likely reference here is to the angels (“sons of God,” cf. Genesis 6:4; Job 1:6; Job 2:1) who came to earth and mingled with women. This interpretation is expounded in the pseudepigraphical book of Enoch, from which Jude quotes in v.14 (also commonly quoted in the intertestamental literature and the early church fathers). These angels “did not keep their positions of authority.” The implication is that God assigned angels stipulated responsibilities and a set place. But because of their rebellion, God has reserved them in darkness and in eternal chains awaiting final judgment. Apparently some fallen angels are in bondage while others are unbound and active among people as demons.
