2 Chronicles 22:11-12

Young's Literal Translation

¹¹ And Jehoshabeath daughter of the king taketh Joash son of Ahaziah, and stealeth him from the midst of the sons of the king who are put to death, and putteth him and his nurse into the inner part of the bed-chambers, and Jehoshabeath daughter of king Jehoram, wife of Jehoiada the priest, because she hath been sister of Ahaziah, hideth him from the face of Athaliah, and she hath not put him to death.

¹² And he is with them in the house of God hiding himself six years, and Athaliah is reigning over the land.
