2 Peter 2:4-9

4For if God did not [even] spare angels that sinned, but threw them into hell and sent them to pits of gloom to be kept [there] for judgment;

5and if He did not spare the ancient world, but protected Noah, a preacher of righteousness, with seven others, when He brought [the judgment of] a flood upon the world of the ungodly;

6and if He condemned the cities of Sodom and Gomorrah to destruction by reducing them to ashes, having made them an example to those who would live ungodly lives thereafter;

7and if He rescued righteous Lot, who was tormented by the immoral conduct of unprincipled and ungodly men

8(for that just man, while living among them, felt his righteous soul tormented day after day by what he saw and heard of their lawless acts),

9then [in light of the fact that all this is true, be sure that] the Lord knows how to rescue the godly from trial, and how to keep the unrighteous under punishment until the day of judgment,
