1 Chronicles 19:9-11

Revised Standard Version

⁹ And the Ammonites came out and drew up in battle array at the entrance of the city, and the kings who had come were by themselves in the open country.

¹⁰ When Jo′ab saw that the battle was set against him both in front and in the rear, he chose some of the picked men of Israel, and arrayed them against the Syrians; ¹¹ the rest of his men he put in the charge of Abi′shai his brother, and they were arrayed against the Ammonites.
