Jude 1:7
In a similar way, Sodom and Gomorrah and the surrounding towns gave themselves up to sexual immorality and perversion, and serve as an example of those who suffer the punishment of eternal fire — Jude cites Sodom and Gomorrah as a second historical instance of divine judgment, associating the false teachers' licentiousness with the cities' sexual depravity and consequent destruction. The phrase 'serve as an example' (deigma, 'display') suggests that their punishment functions pedagogically for the community, demonstrating the serious consequences of covenant-breaking and lawlessness. The reference to 'eternal fire' (aionion pyr) echoes Jewish eschatology and suggests that judgment extends beyond temporal destruction into the age to come.
