8. When David heard of it, he sent Joab and all the army of mighty men.
9. And the Ammonites came out and lined up in battle array before the entrance of the city [Medeba], and the kings who had come were by themselves in the open country.
10. When Joab saw that the battle was set against him before and behind, he chose from all the choice men of Israel and put them in array against the Syrians.
11. The rest of the soldiers he delivered to Abishai his brother, and they were arrayed against the Ammonites.
12. And he said, If the Syrians are too strong for me, then you help me; but if the Ammonites are too strong for you, I will help you.
13. Be of good courage and let us behave ourselves courageously for our people and for the cities of our God; and may the Lord do what is good in His sight.
14. So Joab and the people who were with him drew near before the Syrians for battle, and they fled before him.
15. And when the Ammonites saw that the Syrians fled, they likewise fled before Abishai, Joab's brother, and entered into the city [Medeba]. Then Joab came to Jerusalem.
16. When the Syrians saw that they were defeated by Israel, they sent messengers and drew forth the Syrians who were beyond the Euphrates River, with Shophach the commander of the army of Hadadezer at their head.
17. It was told to David, and he gathered all Israel and crossed the Jordan and drew up his army against them. So when David set the battle in array against the Syrians, they fought with him.
18. But the Syrians fled before Israel, and David slew of the Syrians 7,000 men in chariots and 40,000 foot soldiers, and killed Shophach the commander of the army.
19. When the servants of Hadadezer saw that they were defeated before Israel, they made peace with David and became subject to him; nor would the Syrians any longer help the Ammonites.
