2 Chronicles 22:10-12 - The Reign Of Athaliah

10 Now when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the royal family of the house of Judah. 11 But Jehoshabeath, the daughter of the king, took Joash the son of Ahaziah, and stole him away from among the king's sons who were slain, and put him and his nurse in the bedroom. So Jehoshabeath, the daughter of king Jehoram, the wife of Jehoiada the priest (for she was the sister of Ahaziah), hid him from Athaliah, so that she did not kill him. 12 He was with them hidden in God's house six years: and Athaliah reigned over the land.
