But, I want to remind you, [even] though you already know the stories about how the Lord delivered His people from Egyptian [bondage], and then [later] destroyed those who did not believe [in Him].

And angels, who did not remain within [the bounds of] their proper authority, but left their own realm, God has kept in perpetual bondage, under [thick] darkness, awaiting judgment on the Great Day [when they will be punished].

But, when the ruling angel Michael disputed with the devil over [the final disposal of] the body of Moses, [even] he did not dare to bring derogatory charges against him [i.e., the devil], but said, "May the Lord rebuke you." [Note: Some suggest that this account appeared in an apocryphal book, possibly "The Assumption of Moses"].

But these people [i.e., the "certain men" of verse 4] speak against whatever they do not understand, and what they do understand naturally, the way animals do, proves to be their ruination.

It is too bad for these people, for they have followed the example of Cain [the murderer]; for the sake of money they have rushed into the [same] error as Balaam committed [See Num. 25:1-5; 31:16]; they [will] perish [spiritually] for having rebelled [against God] like Korah did. [See Num. 16:1-3, 31-35].

But you dearly loved ones, you should remember the message that was previously told to you by the apostles of our Lord Jesus Christ,

But, you dearly loved ones, build yourselves up [spiritually] on [the foundation of] your most sacred faith; pray in [the power of] the Holy Spirit.

Now, may there be honor and majesty and power to God, who is able to guard you people from stumbling [and falling away from Him, See Gal. 5:4], and [who is able] to place you before His glorious presence without any [moral] blemish, but with great joy.
