2 Chronicles 22:10–12
When Athaliah the mother of Ahaziah saw that her son was dead, she proceeded to annihilate all the royal heirs of the house of Judah. / But Jehoshabeath daughter of King Jehoram took Joash son of Ahaziah and stole him away from among the sons of the king who were being murdered, and she put him and his nurse in a bedroom. Because Jehoshabeath, the daughter of King Jehoram and the wife of Jehoiada the priest, was Ahaziah’s sister, she hid Joash from Athaliah so that she could not kill him. / And Joash remained hidden with them in the house of God for six years while Athaliah ruled the land.
