1 Chronicles 19:7-15

7So they hired for themselves thirty-two thousand chariots, and the king of Maacah and his people, who came and camped opposite 1Medeba. And the sons of Ammon gathered together from their cities and came to the battle. 8When David heard about it, he sent Joab and all the army, the mighty men. 9The sons of Ammon came out and drew up in battle formation at the entrance of the city; and the kings who had come were by themselves in the field.

10Now when Joab saw that the 2battle was set against him at the front and at the rear, he selected warriors from all the choice men in Israel and lined them up against the Arameans. 11But the remainder of the people he placed 3under the command of 4Abshai his brother; and they lined up against the sons of Ammon. 12He said, “If the Arameans are too strong for me, then you shall help me; but if the sons of Ammon are too strong for you, then I will help you. 13Be strong, and let’s show ourselves courageous for the benefit of our people and the cities of our God; and may the Lord do what is good in His sight.” 14So Joab and the people who were with him advanced to battle against the Arameans, and they fled from him. 15When the sons of Ammon saw that the Arameans had fled, they also fled from his brother Abshai and entered the city. Then Joab came to Jerusalem.
