Genesis 19:27-29

27Early in the morning Abraham went to the place where he had stood before the Lord.

28He looked down toward Sodom and Gomorrah and all the land of the plain, and he saw that smoke was going up from the land like the smoke of a furnace.

29So it was, when God destroyed the cities of the plain, he remembered Abraham and brought Lot out of the middle of the upheaval when he demolished the cities where Lot had lived.
