2 Kings 11:1-2

Darby Translation

11 And when Athaliah the mother of Ahaziah saw that her son was dead, she rose up and destroyed all the royal seed.

² But Jehosheba, the daughter of king Joram, the sister of Ahaziah, took Joash the son of Ahaziah and stole him from among the king's sons that were slain, [and hid] him and his nurse in the bedchamber; and they hid him from Athaliah, so that he was not slain.
