1 Chronicles 18:11-13

18:11 King David dedicated these things to the Lord, along with the silver and gold which he had carried off from all the nations, including Edom, Moab, the Ammonites, the Philistines, and Amalek.

18:12 Abishai son of Zeruiah killed 18,000 Edomites in the Valley of Salt. 18:13 He placed garrisons in Edom, and all the Edomites became David’s subjects. The Lord protected David wherever he campaigned.
