Genesis 19:23-26

By the time Lot reached Zoar, the sun had risen over the land. Then the LORD rained down burning sulphur on Sodom and Gomorrah – from the LORD out of the heavens. Thus he overthrew those cities and the entire plain, destroying all those living in the cities – and also the vegetation in the land. But Lot’s wife looked back, and she became a pillar of salt.
