Genesis 19:23 (KJV)

And Lot said unto them, Oh, not so, my LORD:

Behold now, thy servant hath found grace in thy sight, and thou hast magnified thy mercy, which thou hast shewed unto me in saving my life; and I cannot escape to the mountain, lest some evil take me, and I die:

Behold now, this city is near to flee unto, and it is a little one: Oh, let me escape thither, (is it not a little one?) and my soul shall live.

And he said unto him, See, I have accepted thee concerning this thing also, that I will not overthrow this city, for the which thou hast spoken.

Haste thee, escape thither; for I cannot do anything till thou be come thither. Therefore the name of the city was called Zoar.

Then the LORD rained upon Sodom and upon Gomorrah brimstone and fire from the LORD 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.

But his wife looked back from behind him, and she became a pillar of salt.

And Abraham gat up early in the morning to the place where he stood before the LORD:

And he looked toward Sodom and Gomorrah, and toward all the land of the plain, and beheld, and, lo, the smoke of the country went up as the smoke of a furnace.
