1 Chronicles 19:8-10

Living Bible

⁸ When David learned of this, he sent Joab and the mightiest warriors of Israel. 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.
