Genesis 19:23-30

The sun was high in the sky when Lot arrived at Zoar. Then GOD rained brimstone and fire down on Sodom and Gomorrah—a river of lava from GOD out of the sky!—and destroyed these cities and the entire plain and everyone who lived in the cities and everything that grew from the ground. But Lot’s wife looked back and turned into a pillar of salt. Abraham got up early the next morning and went to the place he had so recently stood with GOD. He looked out over Sodom and Gomorrah, surveying the whole plain. All he could see was smoke belching from the Earth, like smoke from a furnace. And that’s the story: When God destroyed the Cities of the Plain, he was mindful of Abraham and first got Lot out of there before he blasted those cities off the face of the Earth. Lot left Zoar and went into the mountains to live with his two daughters; he was afraid to stay in Zoar. He lived in a cave with his daughters.
