2 Samuel 10:9-11

English Standard Version

⁹ When Joab saw that the battle was set against him both in front and in the rear, he chose some of the best men of Israel and arrayed them against the Syrians. ¹⁰ The rest of his men he put in the charge of Abishai his brother, and he arrayed them against the Ammonites. ¹¹ And he said, “If the Syrians are too strong for me, then you shall help me, but if the Ammonites are too strong for you, then I will come and help you.
