Genesis 19:24-26

Then the LORD rained down brimstone (flaming sulfur) and fire on Sodom and on Gomorrah from the LORD out of heaven, and He overthrew (demolished, ended) those cities, and the entire valley, and all the inhabitants of the cities, and whatever grew on the ground. But Lot’s wife, from behind him, [foolishly, longingly] looked [back toward Sodom in an act of disobedience], and she became a pillar of salt. [Luke 17:32]
