1 Chronicles 19:10-15

10When Joab saw that there was a battle line against him both in front and rear, he selected some of Israel’s best men and deployed them against the Arameans.

11He put the rest of the people under the command of his brother Abishai, and arrayed them against the Ammonites.

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

13Chazak! Take courage for the sake of our people and the cities of our God! Adonai will do what is good in His eyes.”

14So Joab and the people who were with him advanced to battle against the Arameans, and they fled before him.

15When the Ammonites saw that the Arameans had fled, they likewise fled before his brother Abishai and withdrew into the city. Then Joab went to Jerusalem.
