2 Kings 11:1-3

When Athaliah the mother of Ahaziah saw that her son was dead, she rose and destroyed all the royal offspring. 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 who were being put to death, and placed him and his nurse in the bedroom. So they hid him from Athaliah, and he was not put to death. So he was hidden with her in the house of the LORD six years, while Athaliah was reigning over the land.
