Genesis 19:24-29

Yahweh rained down from heaven upon Sodom and Gomorrah brimstone and fire from Yahweh. And he overthrew those cities and the whole plain, and the inhabitants of the cities and the vegetation of the ground. But his wife looked back, and she became a pillar of salt. And Abraham arose early in the morning and went to the place where he had stood before Yahweh. And he looked down upon the surface of Sodom and Gomorrah, and upon the whole surface of the land, the plain. And he saw that, behold, the smoke of the land went up like the smoke of a smelting furnace. So it was, when God destroyed the cities of the plain that God remembered Abraham and sent Lot out from the midst of the overthrow, when he overthrew the cities in which Lot lived.
