'Bedroom' in the Bible

One of his servants said, “No one, my lord the king. Elisha, the prophet in Israel, tells the king of Israel even the words you speak in your bedroom.”

Jehosheba, who was King Jehoram’s daughter and Ahaziah’s sister, secretly rescued Joash son of Ahaziah from the king’s sons who were being killed and put him and the one who nursed him in a bedroom. So he was hidden from Athaliah and was not killed.
