I Kings 15:12-14

And he banished the perverted persons from the land, and removed all the idols that his fathers had made. Also he removed Maachah his grandmother from being queen mother, because she had made an obscene image of Asherah. And Asa cut down her obscene image and burned it by the Brook Kidron. But the high places were not removed. Nevertheless Asa’s heart was loyal to the LORD all his days.
