7 And when David heard of it, he sent Jo'ab and all the host of the mighty men. 8 And the Ammonites came out and drew up in battle array at the entrance of the gate; and the Syrians of Zobah and of Rehob, and the men of Tob and Ma'acah, were by themselves in the open country. 9 When Jo'ab saw that the battle was set against him both in front and in the rear, he chose some of the picked men of Israel, and arrayed them against the Syrians; 10 the rest of his men he put in the charge of Abi'shai his brother, and he arrayed them against the Ammonites. 11 And he said, "If the Syrians are too strong for me, then you shall help me; but if the Ammonites are too strong for you, then I will come and help you. 12 Be of good courage, and let us play the man for our people, and for the cities of our God; and may the Lord do what seems good to him." 13 So Jo'ab and the people who were with him drew near to battle against the Syrians; and they fled before him. 14 And when the Ammonites saw that the Syrians fled, they likewise fled before Abi'shai, and entered the city. Then Jo'ab returned from fighting against the Ammonites, and came to Jerusalem.
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.

Commentary on 2 Samuel 10:6-14
(Read 2 Samuel 10:6-14)
They that are at war with the Son of David, not only give the provocation, but begin the war. God has forces to send against those that set his wrath at defiance, Isaiah 5:19, which will convince them that none ever hardened his heart against God, and prospered. Christ's soldiers should strengthen one another's hands in their spiritual warfare. Let nothing be wanting in us, whatever the success be. When we make conscience of doing our duty, we may, with satisfaction, leave the event with God, assuredly hoping for his salvation in his own way and time.
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.
