Genesis 19:27

Then the LORD rained on Sodom and on Gomorrah sulfur and fire from the LORD out of the sky.

He overthrew those cities, all the plain, all the inhabitants of the cities, and that which grew on the ground.

But Lot’s wife looked back from behind him, and she became a pillar of salt.

He looked toward Sodom and Gomorrah, and toward all the land of the plain, and saw that the smoke of the land went up as the smoke of a furnace.

When God destroyed the cities of the plain, God remembered Abraham, and sent Lot out of the middle of the overthrow, when he overthrew the cities in which Lot lived.

Lot went up out of Zoar, and lived in the mountain, and his two daughters with him; for he was afraid to live in Zoar. He lived in a cave with his two daughters.
