Genesis 19:17, 24-25

And it came to pass, when they had brought them forth abroad, that he said, Escape for thy life; look not behind thee, neither stay thou in all the Plain; escape to the mountain, lest thou be consumed.

Then Jehovah rained upon Sodom and upon Gomorrah brimstone and fire from Jehovah out of heaven; and he overthrew those cities, and all the Plain, and all the inhabitants of the cities, and that which grew upon the ground.
