2 Samuel 10:9-16

Joab saw that there were battle lines in front of him and behind him; so he selected some of the best troops in Israel and deployed them against the Arameans. He put the rest of the men under the command of Abishai his brother and deployed them against the Ammonites. Joab said, “If the Arameans are too strong for me, then you are to come to my rescue; but if the Ammonites are too strong for you, then I will come to rescue you. Be strong, and let us fight bravely for our people and the cities of our God. The LORD will do what is good in his sight.” Then Joab and the troops with him advanced to fight the Arameans, and they fled before him. When the Ammonites realized that the Arameans were fleeing, they fled before Abishai and went inside the city. So Joab returned from fighting the Ammonites and came to Jerusalem. After the Arameans saw that they had been routed by Israel, they regrouped. Hadadezer had Arameans brought from beyond the Euphrates River; they went to Helam, with Shobak the commander of Hadadezer’s army leading them.
