2 Samuel 8:11-13

11King David also dedicated these to the Lord, along with the silver and gold that he had dedicated from all the nations which he had subdued—

12from Syria, from Moab, from the people of Ammon, from the Philistines, from Amalek, and from the spoil of Hadadezer the son of Rehob, king of Zobah.

13And David made himself a name when he returned from killing eighteen thousand Syrians in the Valley of Salt.
