But Jehosheba, daughter of King Jehoram and sister of Ahaziah, took Ahaziah’s son Joash. She saved him from being killed with the king’s other sons, and in a bedroom she hid him and his nurse from Athaliah. So Joash wasn’t killed
In the seventh year of Athaliah’s reign, Jehoiada sent for the company commanders of the Carites and the guards and had them come to him in the Lord’s temple. He made an agreement with them, put them under oath in the Lord’s temple, and showed them the king’s son.
Then he went to his father’s home in Ophrah. There he executed his 70 brothers, Jerubbaal’s sons. But Jotham, Jerubbaal’s youngest son, survived because he hid.
