5 I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.
5 Now I want to remind you, although you once fully knew it, that Jesus, who saved
5 I'm laying this out as clearly as I can, even though you once knew all this well enough and shouldn't need reminding. Here it is in brief: The Master saved a people out of the land of Egypt. Later he destroyed those who defected.
5 But I want to remind you, though you once knew this, that the Lord, having saved the people out of the land of Egypt, afterward destroyed those who did not believe.
5 So I want to remind you, though you already know these things, that Jesus first rescued the nation of Israel from Egypt, but later he destroyed those who did not remain faithful.
Matthew Henry's Commentary on Jude 1:5
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.
