2 Samuel 10:16-19

16Hadadezer had Arameans brought from beyond the Euphrates River; they went to Helam, with Shobak the commander of Hadadezer’s army leading them.

17When David was told of this, he gathered all Israel, crossed the Jordan and went to Helam. The Arameans formed their battle lines to meet David and fought against him.

18But they fled before Israel, and David killed seven hundred of their charioteers and forty thousand of their foot soldiers. He also struck down Shobak the commander of their army, and he died there.

19When all the kings who were vassals of Hadadezer saw that they had been routed by Israel, they made peace with the Israelites and became subject to them. So the Arameans were afraid to help the Ammonites anymore.
