2 Peter 2:5-7

and 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; [Gen 6-8; 1 Pet 3:20] and 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; [Gen 19:24] and if He rescued righteous Lot, who was tormented by the immoral conduct of unprincipled and ungodly men [Gen 19:16, 29]
