2 Samuel 10:17-19

So David mustered Israel, crossed the Jordan, and came to Helam. The Arameans went into battle formation, ready for David, and the fight was on. But the Arameans again scattered before Israel. David killed seven hundred chariot drivers and forty thousand cavalry. And he mortally wounded Shobach, the army commander, who died on the battlefield. When all the kings who were vassals of Hadadezer saw that they had been routed by Israel, they made peace and became Israel’s vassals. The Arameans were afraid to help the Ammonites ever again.
