1 Chronicles 19:7-9

International Standard Version

⁷ They hired 32,000 chariots, along with the king of Maacah and his army, who arrived and encamped at Medeba. The Ammonites also were mustered and came out to battle from their home cities. ⁸ In response, David sent out Joab and his entire army of elite soldiers. ⁹ The Ammonites went out in battle formation in front of the entrance to the city while the kings who had come stayed by themselves in the open fields.
