1 Chronicles 19:6-9

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.
