2 Kings 11:1-3 King James Version (KJV)
11 And when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the seed royal.
2 But Jehosheba, the daughter of king Joram, sister of Ahaziah, took Joash the son of Ahaziah, and stole him from among the king's sons which were slain; and they hid him, even him and his nurse, in the bedchamber from Athaliah, so that he was not slain.
3 And he was with her hid in the house of the Lord six years. And Athaliah did reign over the land.
