2CH 22:11

11 But Jehosheba, the daughter of King Jehoram, took Joash, Ahaziah’s very young son, away from the other sons of the king who were about to be murdered, and she hid him and his nursemaid in a bedroom in the temple. Because Jehosheba, who was the daughter of King Jehoram and the wife of the Supreme Priest Jehoiada, was Ahaziah’s sister, she hid the child, with the result that Athaliah could not kill him.
