2 Samuel 8:11-14

11These too King David consecrated to Adonai, along with the silver and gold that he had consecrated from all the nations that he had subdued:

12from Aram, Moab, the Ammonites, the Philistines, Amalek, and from the spoil of Hadadezer, son of Rehob, king of Zobah.

13Then David made a name for himself when he returned from striking 18,000 down from Edom in the Valley of Salt.

14Then he stationed garrisons in Edom. Throughout all Edom he stationed garrisons, so that all the Edomites became vassals to David. So Adonai gave victory to David wherever he went.
