1 Chronicles 19:9-11

Living Bible

⁹ The army of Ammon went out to meet them and began the battle at the gates of the city of Medeba. Meanwhile, the mercenary forces were out in the field. ¹⁰ When Joab realized that the enemy forces were both in front and behind him, he divided his army and sent one group to engage the Syrians. ¹¹ The other group, under the command of his brother Abishai, moved against the Ammonites.
