2 Kings 11:1-3

Now when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the seed royal. But Jehosheba, the daughter of king Joram, sister of Ahaziah, took Joash the son of Ahaziah, and stole him away from among the king’s sons that were slain, even him and his nurse, and put them in the bedchamber; and they hid him from Athaliah, so that he was not slain; And he was with her hid in the house of Jehovah six years. And Athaliah reigned over the land.
