15 But when the Syrians saw that they had been defeated by Israel, they gathered themselves together. 16 And Hadade'zer sent, and brought out the Syrians who were beyond the Euphra'tes; and they came to Helam, with Shobach the commander of the army of Hadade'zer at their head. 17 And when it was told David, he gathered all Israel together, and crossed the Jordan, and came to Helam. And the Syrians arrayed themselves against David, and fought with him. 18 And the Syrians fled before Israel; and David slew of the Syrians the men of seven hundred chariots, and forty thousand horsemen, and wounded Shobach the commander of their army, so that he died there. 19 And when all the kings who were servants of Hadade'zer saw that they had been defeated by Israel, they made peace with Israel, and became subject to them. So the Syrians feared to help the Ammonites any more.

(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.
