2 Chronicles 26:9-15

Uzziah also built towers in Jerusalem at the Corner Gate, the Valley Gate, and at the corner buttress [of the wall], and fortified them. He also built towers in the wilderness and dug many cisterns, for he had a great deal of livestock, both in the lowlands and in the plain. He also had farmers and vinedressers in the hill country and in the fertile fields, for he loved the soil. Moreover, Uzziah had an army ready for battle, which went into combat by divisions according to the number of their muster as recorded by Jeiel the scribe and Maaseiah the official, under the direction of Hananiah, one of the king’s commanders. The total number of the heads of the fathers’ households, of valiant men, was 2,600. Under their command was an army of 307,500, who could wage war with great power, to help the king against the enemy. Moreover, Uzziah prepared shields, spears, helmets, body armor, bows, and sling stones for the entire army. In Jerusalem he made machines of war invented by skillful men to be put on the towers and on the [corner] battlements for the purpose of shooting arrows and large stones. And his fame spread far, for he was marvelously helped until he was strong.
