Valley of Salt
After receiving the Davidic covenant, the LORD gave victory to David wherever he went. King David dedicated the silver and gold from the nations he subdued, from Edom, Moab, the Ammonites, the Philistines, Amalek, and Hadadezer the son of Rehob, king of Zobah. He made a name for himself when he returned from striking down 18,000 Edomites in the Valley of Salt. David put garrisons throughout all Edom, and all Edomites became David's servants. (2 Samuel 8:11-15)
