1 Chronicles 18:11-13

11King David took those gifts and he offered them to the Lord. He also offered to the Lord all the silver and gold things that he had taken from other nations. Those nations were Edom, Moab, the Ammonites, the Philistines and the Amalekites.

12Zeruiah's son Abishai killed 18,000 men from Edom in the Valley of Salt.

13He put groups of his soldiers in Edom, so that David had authority over all the Edomites. The Lord helped David to win all the battles that he fought.
