1 Kings 15:12-14

He forced the male prostitutes at the worship places to leave the country. He also took away the idols that his ancestors had made. His grandmother Maacah had made a terrible Asherah idol, so Asa removed her from being queen mother. He cut down that idol and burned it in the Kidron Valley. The places of worship to gods were not removed. Even so, Asa was faithful to the LORD all his life.
