7 When David heard of it, he sent Joab, and all the army of the mighty men. 8 The children of Ammon came out, and put the battle in array at the entrance of the gate: and the Syrians of Zobah and of Rehob, and the men of Tob and Maacah, were by themselves in the field. 9 Now when Joab saw that the battle was set against him before and behind, he chose of all the choice men of Israel, and put them in array against the Syrians: 10 The rest of the people he committed into the hand of Abishai his brother; and he put them in array against the children of Ammon. 11 He said, “If the Syrians are too strong for me, then you shall help me; but if the children of Ammon are too strong for you, then I will come and help you. 12 Be of good courage, and let us be strong for our people, and for the cities of our God; and Yahweh do that which seems good to him.” 13 So Joab and the people who were with him drew near to the battle against the Syrians: and they fled before him. 14 When the children of Ammon saw that the Syrians had fled, they likewise fled before Abishai, and entered into the city. Then Joab returned from the children of Ammon, and came to Jerusalem.
15 When the Syrians saw that they were defeated by Israel, they gathered themselves together. 16 Hadadezer sent, and brought out the Syrians who were beyond the River: and they came to Helam, with Shobach the captain of the army of Hadadezer at their head. 17 It was told David; and he gathered all Israel together, and passed over the Jordan, and came to Helam. The Syrians set themselves in array against David, and fought with him. 18 The Syrians fled before Israel; and David killed of the Syrians the men of seven hundred chariots, and forty thousand horsemen, and struck Shobach the captain of their army, so that he died there. 19 When all the kings who were servants to Hadadezer saw that they were defeated before Israel, they made peace with Israel, and served them. So the Syrians feared to help the children of Ammon 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.
