II Samuel 10:7-14

Now when David heard of it, he sent Joab and all the army of the mighty men. Then the people of Ammon came out and put themselves in battle array at the entrance of the gate. And the Syrians of Zoba, Beth Rehob, Ish-Tob, and Maacah were by themselves in the field. When Joab saw that the battle line was against him before and behind, he chose some of Israel’s best and put them in battle array against the Syrians. And the rest of the people he put under the command of Abishai his brother, that he might set them in battle array against the people of Ammon. Then he said, “If the Syrians are too strong for me, then you shall help me; but if the people of Ammon are too strong for you, then I will come and help you. Be of good courage, and let us be strong for our people and for the cities of our God. And may the LORD do what is good in His sight.” So Joab and the people who were with him drew near for the battle against the Syrians, and they fled before him. When the people of Ammon saw that the Syrians were fleeing, they also fled before Abishai, and entered the city. So Joab returned from the people of Ammon and went to Jerusalem.
