2 Samuel 10:8-10

Amplified Bible

⁸ The Ammonites came out and lined up for battle at the entrance of the [city] gate, but the Arameans of Zobah and Rehob and the men of Tob and Maacah were [stationed] by themselves in the field.

⁹ Now when Joab saw that the battlefront was against him in front and in the rear, he selected some of all the choice men in Israel and set them in battle formation to meet the Arameans (Syrians). ¹⁰ But he placed the rest of the men in the hand of his brother Abishai, and he placed them in battle formation to meet the Ammonites.
