2 Samuel 10:14-18

When the sons of Ammon saw that the Arameans had fled, they also fled from Abishai and entered the city. Then Joab returned from fighting against the sons of Ammon and came to Jerusalem.

When the Arameans saw that they had been defeated by Israel, they assembled together.

And Hadadezer sent word and brought out the Arameans who were beyond the Euphrates River, and they came to Helam; and Shobach the commander of the army of Hadadezer led them.

Now when it was reported to David, he gathered all Israel together and crossed the Jordan, and came to Helam. And the Arameans lined up against David and fought him.

But the Arameans fled from Israel, and David killed seven hundred charioteers of the Arameans and forty thousand horsemen, and struck Shobach the commander of their army, and he died there.
