1 Chronicles 19:6-15

International Standard Version

⁶ When the Ammonites realized that they had created quite a stink with David, Hanun and the Ammonites spent 1,000 silver talents^[a] to hire chariots and mercenaries from Mesopotamia, from Aram-maacah, and from Zobah. 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.

¹⁰ When Joab observed that the battle lines were set up to oppose him both in front and behind, he appointed some special forces from Israel and arrayed them to oppose the Arameans, ¹¹ putting the rest of his forces under command of his brother Abishai, who arrayed them to oppose the Ammonites. ¹² He told Abishai,^[b] “If the Arameans prove too strong for me, then you are to help me. If the Ammonites prove too strong for you, then I will help you. ¹³ Be strong, be courageous on behalf of our people and for the cities of our God, and may the Lord do what he thinks is best.” ¹⁴ So Joab and the soldiers who were with him attacked the Arameans in battle formation, and the Arameans retreated in front of him. ¹⁵ When the Ammonites saw the Arameans retreating, they also retreated from Joab’s brother Abishai back to the city and Joab left for Jerusalem.
