1 Chronicles 19:6-8

New Revised Standard Version, Anglicised

⁶ When the Ammonites saw that they had made themselves odious to David, Hanun and the Ammonites sent a thousand talents of silver to hire chariots and cavalry from Mesopotamia, from Aram-maacah and from Zobah. ⁷ They hired thirty-two thousand chariots and the king of Maacah with his army, who came and camped before Medeba. And the Ammonites were mustered from their cities and came to battle. ⁸ When David heard of it, he sent Joab and all the army of the warriors.
