2 Chronicles 14:5
Also he took away out of all the cities of Judah the high places and the images: and the kingdom was quiet before him. Also he took away out of all the cities of Judah the high places and the images: and the kingdom was quiet before him.
Asa took away the high places and the images out of all the cities throughout Judah. The images removed were sun images. This removal was part of his reform. By clearing these objects away he worked to lead the people to seek God and to obey His commandments. As a result the kingdom was quiet and at peace under his rule, enjoying rest during his reign.
