Salt

David also made himself a name, when he returned after taking Syria in the valley of the saltpits, killing eighteen thousand:

He slew of Edom in the valley of the Saltpits, ten thousand men, and took the rock by war, and called the name thereof Jectehel, unto this day.

And Abisai the son of Sarvia slew of the Edomites in the vale of the saltpits, eighteen thousand:

And Amasias taking courage led forth his people, and went to the vale of saltpits, and slew of the children of Seir ten thousand.

Unto the end, in hymns, for David.
