1 Kings 15:13

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.

And also Maachah his mother, even her he removed from being queen, because she had made an idol in a grove; and Asa destroyed her idol, and burnt it by the brook Kidron.
