5 But I would put you in remembrance, you who once knew all things, that the Lord, having saved a people out of [the] land of Egypt, in the second place destroyed those who had not believed. 6 And angels who had not kept their own original state, but had abandoned their own dwelling, he keeps in eternal chains under gloomy darkness, to [the] judgment of [the] great day; 7 as Sodom and Gomorrha, and the cities around them, committing greedily fornication, in like manner with them, and going after other flesh, lie there as an example, undergoing the judgment of eternal fire.

Matthew Henry's Commentary on Jude 1:5-7

Commentary on Jude 1:5-7

(Read Jude 1:5-7)

Outward privileges, profession, and apparent conversion, could not secure those from the vengeance of God, who turned aside in unbelief and disobedience. The destruction of the unbelieving Israelites in the wilderness, shows that none ought to presume on their privileges. They had miracles as their daily bread; yet even they perished in unbelief. A great number of the angels were not pleased with the stations God allotted to them; pride was the main and direct cause or occasion of their fall. The fallen angels are kept to the judgment of the great day; and shall fallen men escape it? Surely not. Consider this in due time. The destruction of Sodom is a loud warning to all, to take heed of, and flee from fleshly lusts that war against the soul, Job 15:16.
