1 Chronicles 19:7-9

New Century Version

⁷ The Ammonites hired thirty-two thousand chariots and the king of Maacah and his army. So they came and set up camp near the town of Medeba. The Ammonites themselves came out of their towns and got ready for battle.

⁸ When David heard about this, he sent Joab with the whole army. ⁹ The Ammonites came out and prepared for battle at the city gate. The kings who had come to help were out in the field by themselves.
