'Salty' in the Bible

and a fruitful land into a salty waste, due to the wickedness of its inhabitants.

Therefore as I'm alive and living," declares the LORD of the Heavenly Armies, the God of Israel, "Moab will surely become like Sodom, and the Ammonites like Gomorrah, a place overrun by weeds and salty marshes, unpopulated forever. The survivors of my people will confiscate their property, and those who remain of my nation will inherit what was theirs.

"You are the salt of the world. But if the salt should lose its taste, how can it be made salty again? It's good for nothing but to be thrown out and trampled on by people.
