7 And when David heard of it, he sent Joab, and all the host of the mighty men. 8 And 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 And 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 And he said, If the Syrians be too strong for me, then thou shalt help me; but if the children of Ammon be too strong for thee, then I will come and help thee. 12 Be of good courage, and let us play the man for our people, and for the cities of our God: and Jehovah do that which seemeth him good. 13 So Joab and the people that were with him drew nigh unto the battle against the Syrians: and they fled before him. 14 And when the children of Ammon saw that the Syrians were fled, they likewise fled before Abishai, and entered into the city. Then Joab returned from the children of Ammon, and came to Jerusalem.
15 And when the Syrians saw that they were put to the worse before Israel, they gathered themselves together. 16 And Hadarezer sent, and brought out the Syrians that were beyond the River: and they came to Helam, with Shobach the captain of the host of Hadarezer at their head. 17 And it was told David; and he gathered all Israel together, and passed over the Jordan, and came to Helam. And the Syrians set themselves in array 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 smote Shobach the captain of their host, so that he died there. 19 And when all the kings that were servants to Hadarezer saw that they were put to the worse 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.
