Genesis 19:17, 24-25

So it came to pass, when they had brought them outside, that he said, “Escape for your life! Do not look behind you nor stay anywhere in the plain. Escape to the mountains, lest you be destroyed.”

Then the LORD rained brimstone and fire on Sodom and Gomorrah, from the LORD out of the heavens. So He overthrew those cities, all the plain, all the inhabitants of the cities, and what grew on the ground.
