15 When the Arameans saw how badly they'd been beaten by Israel, they picked up the pieces and regrouped. 16 Hadadezer sent for the Arameans who were across the River. They came to Helam. Shobach, commander of Hadadezer's army, led them. 17 All this was reported to David. 18 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.

Commentary on 2 Samuel 10:15-19
(Read 2 Samuel 10:15-19)
Here is a new attempt of the Syrians. Even the baffled cause will make head as long as there is any life in it; the enemies of the Son of David do so. But now the promise made to Abraham, Joshua 1:4, that the borders of Israel should extend to the river Euphrates, was performed. Learn hence, that it is dangerous to help those who have God against them; for when they fall, their helpers will fall with them.
