2 Kings 11:1-3 NIV

[1] When Athaliah the mother of Ahaziah saw that her son was dead, she proceeded to destroy the whole royal family. [2] But Jehosheba, the daughter of King Jehoram and sister of Ahaziah, took Joash son of Ahaziah and stole him away from among the royal princes, who were about to be murdered. She put him and his nurse in a bedroom to hide him from Athaliah; so he was not killed. [3] He remained hidden with his nurse at the temple of the LORD for six years while Athaliah ruled the land.
