2 Chronicles 26:9-10

9Uzziah also built towers in Jerusalem at the Corner Gate, the Valley Gate, and at the corner buttress [of the wall], and fortified them.

10He 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.
