1 Chronicles 19:6-15

New International Version

⁶ When the Ammonites realized that they had become obnoxious^(A) to David, Hanun and the Ammonites sent a thousand talents^[a] of silver to hire chariots and charioteers from Aram Naharaim,^[b] Aram Maakah and Zobah.^{(B) 7} They hired thirty-two thousand chariots and charioteers, as well as the king of Maakah with his troops, who came and camped near Medeba,^(C) while the Ammonites were mustered from their towns and moved out for battle.

⁸ On hearing this, David sent Joab out with the entire army of fighting men. ⁹ The Ammonites came out and drew up in battle formation at the entrance to their city, while the kings who had come were by themselves in the open country.

¹⁰ Joab saw that there were battle lines in front of him and behind him; so he selected some of the best troops in Israel and deployed them against the Arameans. ¹¹ He put the rest of the men under the command of Abishai^(D) his brother, and they were deployed against the Ammonites. ¹² Joab said, “If the Arameans are too strong for me, then you are to rescue me; but if the Ammonites are too strong for you, then I will rescue you. ¹³ Be strong, and let us fight bravely for our people and the cities of our God. The Lord will do what is good in his sight.”

¹⁴ Then Joab and the troops with him advanced to fight the Arameans, and they fled before him. ¹⁵ When the Ammonites realized that the Arameans were fleeing, they too fled before his brother Abishai and went inside the city. So Joab went back to Jerusalem.
