2 Chronicles 26:4-6

4And he did what was right in the eyes of the Lord, according to all that his father Amaziah had done.

5He set himself to seek God in the days of Zechariah, who instructed him in the fear of God, and as long as he sought the Lord, God made him prosper.

6He went out and made war against the Philistines and broke through the wall of Gath and the wall of Jabneh and the wall of Ashdod, and he built cities in the territory of Ashdod and elsewhere among the Philistines.
