2 Chronicles 26:9-15

Uzziah built towers in Jerusalem at the Corner Gate, at the Valley Gate and at the angle of the wall, and he fortified them. He also built towers in the wilderness and dug many cisterns, because he had much livestock in the foothills and in the plain. He had people working his fields and vineyards in the hills and in the fertile lands, for he loved the soil. Uzziah had a well-trained army, ready to go out by divisions according to their numbers as mustered by Jeiel the secretary and Maaseiah the officer under the direction of Hananiah, one of the royal officials. The total number of family leaders over the fighting men was 2,600. Under their command was an army of 307,500 men trained for war, a powerful force to support the king against his enemies. Uzziah provided shields, spears, helmets, coats of armor, bows and slingstones for the entire army. In Jerusalem he made devices invented for use on the towers and on the corner defenses so that soldiers could shoot arrows and hurl large stones from the walls. His fame spread far and wide, for he was greatly helped until he became powerful.
