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

10 And Athaliah the mother of Ahaziah saw that her son was dead, and she arose and spoke to destroy all the royal seed of the house of Judah. 11 But Jehoshabeath the daughter of the king took Joash the son of Ahaziah, and stole him from among the king's sons who were killed. And she put him and his nurse in a bedroom. And 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 And he was with them six years, hidden in the house of God. And Athaliah reigned over the land.
