1 Chronicles 19:6-8

New Century Version

⁶ The Ammonites knew that they had insulted David. So Hanun and the Ammonites sent about seventy-four thousand pounds of silver to hire chariots and chariot drivers from Northwest Mesopotamia, Aram Maacah, and Zobah. ⁷ The Ammonites hired thirty-two thousand chariots and the king of Maacah and his army. So they came and set up camp near the town of Medeba. The Ammonites themselves came out of their towns and got ready for battle.

⁸ When David heard about this, he sent Joab with the whole army.
