Genesis 19:23-30

The sun had already come up when Lot entered Zoar. The LORD sent a rain of burning sulfur down from the sky on Sodom and Gomorrah and destroyed those cities. He also destroyed the whole Jordan Valley, everyone living in the cities, and even all the plants. 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. Lot was afraid to continue living in Zoar, so he and his two daughters went to live in the mountains in a cave.
