1 Kings 15:12-14

12He expelled the male shrine prostitutes from the land and got rid of all the idols his ancestors had made. 13He even deposed his grandmother Maakah from her position as queen mother, because she had made a repulsive image for the worship of Asherah. Asa cut it down and burned it in the Kidron Valley. 14Although he did not remove the high places, Asa’s heart was fully committed to the Lord all his life.
