8. The Ammonites marched out and lined up for battle at the entrance of their city gate, while the Arameans of Zobah and Rehob and the men of Tob and Maacah remained apart in the open field.
9. When Joab saw that there was a battle line both in front of and behind him, he chose some of the best fighters of Israel and lined them up against the Arameans;
10. the rest of the army he placed under the command of his brother Abishai and lined up to oppose the Ammonites.
11. And he said, “If the Arameans prove too strong for me, you must come and save me; and if the Ammonites prove too strong for you, I will come to save you.
12. Hold firm and let us show ourselves courageous for the sake of our people and the cities of our God; and may the Lord do what is good in his sight.”
13. Joab therefore advanced with his men for battle with the Arameans, but they fled before him.
14. And when the Ammonites saw that the Arameans had fled, they too fled before Abishai, and reentered their city. Joab then ceased his attack on the Ammonites and came to Jerusalem.
15. Seeing themselves vanquished by Israel, the Arameans held a full muster of troops.
16. Hadadezer sent for and brought Arameans from beyond the River. They came to Helam, with Shobach, the captain of Hadadezer’s army, at their head.
17. When this was reported to David, he gathered all Israel together, crossed the Jordan, and went to Helam. The Arameans drew up in formation against David and gave battle.
18. But the Arameans fled before Israel, and David killed seven hundred of their chariot fighters and forty thousand of their foot soldiers. He struck down Shobach, commander of the army, and he died on the field.
19. When Hadadezer’s vassal kings saw themselves vanquished by Israel, they made peace with the Israelites and became their subjects. After this, the Arameans were afraid to give further aid to the Ammonites.
