1 Chronicles 18:11-13

Amplified Bible

¹¹ King David also dedicated these to the Lord [setting them apart for sacred use], with the silver and the gold which he brought from all the nations: from Edom, Moab, the Ammonites, the Philistines, and from Amalek.

¹² Also Abishai the son of Zeruiah [David’s half sister] defeated 18,000 Edomites in the Valley of Salt. ¹³ He put military outposts in Edom, and all the Edomites became David’s servants. Thus the Lord helped David wherever he went.
