2 Samuel 10:9-11

International Standard Version

⁹ When Joab observed that the battle lines were set up to oppose him both in front and behind, he appointed the best troops in Israel and arrayed them to oppose the Arameans, ¹⁰ putting the rest of his forces under the command of his brother Abishai, who arrayed them to oppose the Ammonites. ¹¹ He said, “If the Arameans prove too strong for me, then you are to help me. If the Ammonites prove too strong for you, then I will come help you.
