1 Chronicles 19:6-7

When the people of Ammon realized how seriously they had angered David, Hanun and the Ammonites sent 75,000 pounds of silver to hire chariots and charioteers from Aram-naharaim, Aram-maacah, and Zobah. They also hired 32,000 chariots and secured the support of the king of Maacah and his army. These forces camped at Medeba, where they were joined by the Ammonite troops that Hanun had recruited from his own towns.
