Genesis 19:23-29

The sun had risen over the earth when Lot came to Zoar. Then the LORD rained on Sodom and Gomorrah brimstone and fire from the LORD out of heaven, and He overthrew those cities, and all the valley, and all the inhabitants of the cities, and what grew on the ground. But his wife, from behind him, looked back, and she became a pillar of salt. Now Abraham arose early in the morning and went to the place where he had stood before the LORD; and he looked down toward Sodom and Gomorrah, and toward all the land of the valley, and he saw, and behold, the smoke of the land ascended like the smoke of a furnace. Thus it came about, when God destroyed the cities of the valley, that God remembered Abraham, and sent Lot out of the midst of the overthrow, when He overthrew the cities in which Lot lived.
