In the seventh year Jehoiada made a bold move. He made a pact with the officers of the units of hundreds: Azariah son of Jehoram, Ishmael son of Jehochanan, Azariah son of Obed, Maaseiah son of Adaiah, and Elishaphat son of Zikri.

He launched a military campaign against the king of the Ammonites and defeated them. That year the Ammonites paid him 100 talents of silver, 10,000 kors of wheat, and 10,000 kors of barley. The Ammonites also paid this same amount of annual tribute the next two years.
