2 Samuel 8:12-14

Brenton(i) 12 out of Idumea, and out of Moab, and from the children of Ammon, and from the Philistines, and from Amalec, and from the spoils of Adraazar son of Raab king of Suba. 13 And David made himself a name: and when he returned he smote Idumea in Gebelem to the number of eighteen thousand. 14 And he set garrisons in Idumea, even in all Idumea: and all the Idumeans were servants to the king. And the Lord preserved David wherever he went.
