2 Chronicles 14:5-7

5He also removed the high places and incense altars from all the cities of Judah, and under him the kingdom was at peace.

6Because the land was at peace, Asa built fortified cities in Judah. In those days no one made war with him, because the LORD had given him rest. 7So he said to the people of Judah, “Let us build these cities and surround them with walls and towers, with doors and bars. The land is still ours because we have sought the LORD our God. We have sought Him, and He has given us rest on every side.” So they built and prospered.
