'Salt' in the Bible

The Arabah and the Jordan River were also a border, from the sea of Chinnereth to the sea of the Arabah (that is, the Salt Sea), beneath the watershed of Pisgah to the east.

The whole land will be covered with brimstone, salt, and burning debris; it will not be planted nor will it sprout or produce grass. It will resemble the destruction of Sodom and Gomorrah, Admah and Zeboiim, which the Lord destroyed in his intense anger.
