1 Kings 15:13

And he removed Ana his mother from being queen, forasmuch as she gathered a meeting in her grove: and Asa cut down her retreats, and burnt them with fire in the brook of Kedron.

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.

He also removed Maacah his mother from being queen, because she had made an abominable image for an Asherah. Asa cut down her image and burned it at the brook Kidron.
