2 Samuel 10:14-19

14 When the Ammonites saw that the Arameans were running away, they also ran away from Abishai and went back to their city. So Joab returned from the battle with the Ammonites and came to Jerusalem.
15 When the Arameans saw that Israel had defeated them, they came together into one big army.
16 Hadadezer sent messengers to bring the Arameans from east of the Euphrates River, and they went to Helam. Their leader was Shobach, the commander of Hadadezer's army.
17 When David heard about this, he gathered all the Israelites together. They crossed over the Jordan River and went to Helam. There the Arameans prepared for battle and attacked him.
18 But the Arameans ran away from the Israelites. David killed seven hundred Aramean chariot drivers and forty thousand Aramean horsemen. He also killed Shobach, the commander of the Aramean army.
19 When the kings who served Hadadezer saw that the Israelites had defeated them, they made peace with the Israelites and served them. And the Arameans were afraid to help the Ammonites again.
