15 And when the Aramaeans saw that Israel had overcome them, they got themselves together. 16 And Hadadezer sent for the Aramaeans who were on the other side of the River: and they came to Helam, with Shobach, the captain of Hadadezer's army, at their head. 17 And word of this was given to David: and he got all Israel together and went over Jordan and came to Helam. And the Aramaeans put their forces in position against David, and made an attack on him. 18 And the Aramaeans went in flight before Israel; and David put to the sword the men of seven hundred Aramaean war-carriages and forty thousand footmen, and Shobach, the captain of the army, was wounded, and came to his death there.

(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.
