2 Chronicles 22:11 CSB

[11] Jehoshabeath, the king's daughter, rescued Joash son of Ahaziah from the king's sons who were being killed and put him and the one who nursed him in a bedroom. Now Jehoshabeath was the daughter of King Jehoram and the wife of the priest Jehoiada. Since she was Ahaziah's sister, she hid Joash from Athaliah so that she did not kill him.
