Salt of the earth

H. Clay Trumbull The Covenant of Salt

Yet this doomed and dead sea of salt is a source of life to man in its exhaustless supply of salt for his use. Preeminently is this salt of the Dead Sea a savor of life and of death.
The salt of the ocean is the world's treasure. Without it the greater portion of the earth's inhabitants would perish for lack of what vivifies and preserves animal life. Yet because of the salt in the ocean the very water, which man and beast must have or perish of thirst, is useless to both man and beast.

Poems. "The Salt of the Earth."
The salt of the earth—what a meaningful phrase
From the lips of the Saviour, and one that conveys
A sense of the need of a substance saline
This pestilent sphere to refresh and refine,
And a healthful and happy condition secure
By making it pure as the ocean is pure.

Portrait of Robert S. Ball Robert S. Ball The Earth's Beginning

When the earth had become sufficiently cool to permit of the vapours now forming the ocean passing from the gaseous to the liquid form, the oceans descended from the heavens above to the earth beneath in the form of fresh water. In the lapse of subsequent ages the sea has become salt because ordinary river water, which always contains some small quantity of salt in solution, is continually bearing salt down to the sea.
