Genesis 19:26-29

At that point Lot’s wife looked back. When she did, she became a pillar of salt. Early the next morning, Abraham got up and went to the place where he had stood before the LORD. He looked down toward Sodom and Gomorrah and all the Jordan Valley and saw smoke rising from the land, like smoke from a furnace. God destroyed the cities in the valley, but he remembered what Abraham had asked. So God saved Lot’s life, but he destroyed the city where Lot had lived.
