2 Chronicles 22:11

11 But Ahaziah’s sister Jehosheba, the daughter of King Jehoram, took Ahaziah’s infant son, Joash, and stole him away from among the rest of the king’s children, who were about to be killed. She put Joash and his nurse in a bedroom. In this way, Jehosheba, wife of Jehoiada the priest and sister of Ahaziah, hid the child so that Athaliah could not murder him.
