1 Chronicles 19:6-7

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