'Salt' in the Bible

Elisha said, "Get me a new jar and put some salt in it." So they got it.

He went out to the spring and threw the salt in. Then he said, "This is what the Lord says, 'I have purified this water. It will no longer cause death or fail to produce crops."

He defeated 10,000 Edomites in the Salt Valley; he captured Sela in battle and renamed it Joktheel, a name it has retained to this very day.
