2 Chronicles 26:9-10

9Uzziah built strong towers on Jerusalem's walls to make the city safe. He built them at the Corner Gate, at the Valley Gate and at the place where the wall turned.

10He also built towers in the desert. He dug holes in the ground to contain water. He needed water for his animals on the low hills and in the valleys, because he had many of them. He also enjoyed growing crops. He had men who worked in the fields and in the vineyards. These were on the hills and in places where crops would grow well.
