Genesis 19:26-29

But his wife looked back from behind him, and she became a pillar of salt. And Abraham gat up early in the morning to the place where he had stood before Jehovah: and he looked toward Sodom and Gomorrah, and toward all the land of the Plain, and beheld, and, lo, the smoke of the land went up as the smoke of a furnace. And it came to pass, when God destroyed the cities of the Plain, that God remembered Abraham, and sent Lot out of the midst of the overthrow, when he overthrew the cities in which Lot dwelt.
