1 Chronicles 19:10-15

10Now when Joab saw that the 1battle 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 2under the command of 3Abshai 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.
