1 Chronicles 18:3-4

3David also won a battle against Hadadezer, king of Zobah. He won land as far as Hamath. That happened when Hadadezer took his army to the Euphrates river to show that he had authority there.

4David took from Hadadezer 1,000 chariots and 7,000 men who drove them. He also caught 20,000 of Hadadezer's other soldiers. David kept 100 horses that pulled chariots. But he cut the legs of the other horses so that they could not run.
