1 Chronicles 19:6-7

When it dawned on the Ammonites that as far as David was concerned, they stank to high heaven, they hired, at a cost of a thousand talents of silver (thirty-seven and a half tons!), chariots and horsemen from the Arameans of Naharaim, Maacah, and Zobah—thirty-two thousand chariots and drivers; plus the king of Maacah with his troops who came and set up camp at Medeba; the Ammonites, too, were mobilized from their cities and got ready for battle.
