2 Chronicles 26:7

And he sought God in the days of Zechariah, who had understanding in the visions of God: and as long as he sought the LORD, God made him to prosper.

And he went forth and warred against the Philistines, and brake down the wall of Gath, and the wall of Jabneh, and the wall of Ashdod, and built cities about Ashdod, and among the Philistines.

And the Ammonites gave gifts to Uzziah: and his name spread abroad even to the entering in of Egypt; for he strengthened himself exceedingly.

Moreover Uzziah built towers in Jerusalem at the corner gate, and at the valley gate, and at the turning of the wall, and fortified them.
