Genesis 19: 23-26
23 The sun was risen upon the earth when Lot entered into Zoar.
24 Then the LORD rained upon Sodom and upon Gomorrah brimstone and fire from the LORD out of heaven;
25 And he overthrew those cities, and all the plain, and all the inhabitants of the cities, and that which grew upon the ground.
26 But his wife looked back from behind him, and she became a pillar of salt.
Lot’s wife disobeyed God and turned back to the city and basically was turned into ash.
“Lot’s wife, biblical character, a disobedient woman who was turned into a pillar of salt for looking back to see the destruction of Sodom and Gomorrah as she and her family were fleeing. Her story is seen as an example of what happens to those who choose a worldly life over salvation.”
