Genesis 19:26

24Then the LORD rained upon Sodom and upon Gomorrah brimstone and fire from the LORD out of heaven;

25And he overthrew those cities, and all the plain, and all the inhabitants of the cities, and that which grew upon the ground.

26But his wife looked back from behind him, and she became a pillar of salt.

27And Abraham gat up early in the morning to the place where he stood before the LORD:

28And he looked toward Sodom and Gomorrah, and toward all the land of the plain, and beheld, and, lo, the smoke of the country went up as the smoke of a furnace.
