"Prove" the following:

<<Then the Lord rained on Sodom and Gomorrah brimstone and fire from the Lord out of heaven; and he overthrew those cities, and all the valley, and all the inhabitants of the cities, and what grew on the ground.>>

"Prove" the following:

<<But Lot’s wife behind him looked back, and she became a pillar of salt.>>
