1 Chronicles 18:11-13

Brenton(i) 11 And all the golden and silver and brazen vessels, even these king David consecrated to the Lord, with the silver and the gold which he took from all the nations; from Idumaea, and Moab, and from the children of Ammon, and from the Philistines, and from Amalec. 12 And Abesa son of Saruia smote the Idumeans in the valley of Salt, eighteen thousand. 13 And he put garrisons in the valley; and all the Idumaeans became David's servants: and the Lord delivered David wherever he went.
