Genesis 19:28-32

and he looked down toward Sodom and Gomorrah, and toward all the land of the surrounding area; and behold, he saw the smoke of the land ascended like the smoke of a furnace.

So it came about, when God destroyed the cities of the surrounding area, that God remembered Abraham, and sent Lot out of the midst of the destruction, when He overthrew the cities in which Lot had lived. Lot and His Daughters

Now Lot went up from Zoar with his two daughters and stayed in the mountains, because he was afraid to stay in Zoar; and he stayed in a cave, he and his two daughters.

Then the firstborn said to the younger, “Our father is old, and there is not a man on earth to have relations with us according to the custom of all the earth.

Come, let’s make our father drink wine, and let’s sleep with him so that we may keep our family alive through our father.”
