2 Chronicles 27:3-6

Jotham rebuilt the upper gate of the Temple of the LORD. He also did extensive rebuilding on the wall at the hill of Ophel. He built towns in the hill country of Judah and constructed fortresses and towers in the wooded areas. Jotham went to war against the Ammonites and conquered them. Over the next three years he received from them an annual tribute of 7,500 pounds of silver, 50,000 bushels of wheat, and 50,000 bushels of barley. King Jotham became powerful because he was careful to live in obedience to the LORD his God.
