1 Chronicles 19:9-11

New International Version - UK

⁹ The Ammonites came out and drew up in battle formation at the entrance to their city, while the kings who had come were by themselves in the open country.

¹⁰ Joab saw that there were battle lines in front of him and behind him; so he selected some of the best troops in Israel and deployed them against the Arameans. ¹¹ He put the rest of the men under the command of Abishai his brother, and they were deployed against the Ammonites.
