But Jehoshabeath, the daughter of the king, took Joash the son of Ahaziah, and stole him from among the king’s sons that were slain, and put him and his nurse in a bedchamber. So Jehoshabeath, the daughter of king Jehoram, the wife of Jehoiada the priest, (for she was the sister of Ahaziah,) hid him from Athaliah, so that she slew him not.
Berean Study Bible (BSB) - 2 Chronicles 22:11 >But Jehoshabeath daughter of King Jehoram took Joash son of Ahaziah and stole him away from among the sons of the king who were being murdered, and she put him and his nurse in a bedroom. Because Jehoshabeath, the daughter of King Jehoram and the wife of Jehoiada the priest, was Ahaziah’s sister, she hid Joash from Athaliah so that she could not kill him.
