2 Chronicles 27:5-6

He waged war against the king of the Ammonites. He overpowered the Ammonites, and that year they gave him 7,500 pounds  of silver, 60,000 bushels  of wheat, and 60,000 bushels of barley. They paid him the same in the second and third years. So Jotham strengthened his position because he did not waver in obeying  the LORD his God.
