2 Chronicles 14:4-7

He commanded the people of Judah to seek the LORD, the God of their ancestors, and to obey his law and his commands. Asa also removed the pagan shrines, as well as the incense altars from every one of Judah’s towns. So Asa’s kingdom enjoyed a period of peace. During those peaceful years, he was able to build up the fortified towns throughout Judah. No one tried to make war against him at this time, for the LORD was giving him rest from his enemies. Asa told the people of Judah, “Let us build towns and fortify them with walls, towers, gates, and bars. The land is still ours because we sought the LORD our God, and he has given us peace on every side.” So they went ahead with these projects and brought them to completion.
