Genesis 19:23-30

The sun had risen over the earth when Lot came to Zoar. 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] Abraham started out early the next morning to the place where he [only the day before] had stood before the LORD; and he looked down toward Sodom and Gomorrah, and toward all the land of the valley [of the Dead Sea]; and he saw, and behold, the smoke of the land went up like the smoke of a kiln (pottery furnace). Now when God ravaged and destroyed the cities of the plain [of Siddim], He remembered Abraham [and for that reason], and He sent [Abraham’s nephew] Lot out of the midst of the destruction, when He destroyed the cities in which Lot had lived. Now Lot went up from Zoar, and lived in the mountain together with his two daughters, for he was afraid to stay [any longer] in Zoar; and he lived in a cave with his two daughters.
