He also removed his grandmother Maacah from her position as queen mother because she had made a detestable Asherah pole. Asa chopped down the pole and burned it in the Kidron Valley.
He removes Maacah from being queen mother because of her Asherah pole, then cuts it down and burns it in the Kidron Valley.
It shows reform reaching into the royal household itself.
9In the twentieth year of Jeroboam’s reign over Israel, Asa became king of Judah, 10and he reigned in Jerusalem forty-one years. His grandmother’s name was Maacah daughter of Abishalom. 11And Asa did what was right in the eyes of the LORD, as his father David had done. 12He banished the male shrine prostitutes from the land and removed all the idols that his fathers had made. 13He also removed his grandmother Maacah from her position as queen mother because she had made a detestable Asherah pole. Asa chopped down the pole and burned it in the Kidron Valley. 14The high places were not removed, but Asa’s heart was fully devoted to the LORD all his days. 15And he brought into the house of the LORD the silver and gold and the articles that he and his father had dedicated.
