Beloved, while I was making every effort to write you about our common salvation, I was compelled to write to you [urgently] appealing that you fight strenuously for [the defense of] the faith which was once for all handed down to the saints [the faith that is the sum of Christian belief that was given verbally to believers].

For some people have slipped in among you unnoticed. They were written about long ago as being deserving of this condemnation because they are ungodly. They turn the grace of our God into uncontrollable lust and deny our only Master and Lord, Jesus the Messiah.

as Sodom and Gomorrah and the towns around them indulged in sexual immorality and {pursued unnatural desire} [in] the same way as these, are exhibited as an example [by] undergoing the punishment of eternal fire.

Despite that, in the same way also these [men], [because of their] dreams, defile the flesh and reject authority and blaspheme majestic beings.

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"].

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].

These people are gripers and complainers, living according to their own [evil] desires, whose mouths speak boastfully, and who show partiality [toward certain people] to gain some advantage.

And of some have compassion, making a difference:

and some save, snatching them out of the fire; and on some have mercy with fear; hating even the garment spotted by the flesh.
