1 Chronicles 19:10-15

10Now when Joab saw that the battle was set against him in the front and in the rear, he chose warriors from all the choice men of Israel and put them in formation against the Arameans (Syrians).

11The rest of the soldiers he placed in the hand of Abishai his brother, and they lined up against the Ammonites.

12He said, “If the Arameans are too strong for me, then you shall help me; but if the Ammonites are too strong for you, I will help you.

13Be strong and let us show ourselves courageous for the sake of our people and for 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 approached the Arameans for battle, and they fled before him.

15When the Ammonites saw that the Arameans fled, they also fled before Abishai, Joab’s brother, and entered the city [Medeba]. Then Joab came to Jerusalem.
