1 Kings 15:10-13

10And he reigned forty-one years in Jerusalem. His grandmother’s name was Maachah the granddaughter of Abishalom.

11Asa did what was right in the eyes of the Lord, as did his father David.

12And he banished the perverted persons from the land, and removed all the idols that his fathers had made.

13Also 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.
