2 Samuel 8:2-9
English Standard Version
3David also defeated Hadadezer the son of Rehob, king of Zobah, as he went to restore his power at the river Euphrates.
4And David took from him 1,700 horsemen, and 20,000 foot soldiers. And David hamstrung all the chariot horses but left enough for 100 chariots.
5And when the Syrians of Damascus came to help Hadadezer king of Zobah, David struck down 22,000 men of the Syrians.
6Then David put garrisons in Aram of Damascus, and the Syrians became servants to David and brought tribute. And the Lord gave victory to David wherever he went.
7And David took the shields of gold that were carried by the servants of Hadadezer and brought them to Jerusalem.
8And from Betah and from Berothai, cities of Hadadezer, King David took very much bronze.
