'Bedchamber' in the Bible

And one of his servants said, None, my lord, O king: but Elisha, the prophet that is in Israel, telleth the king of Israel the words that thou speakest in thy bedchamber.

But Jehosheba, the daughter of king Joram, sister of Ahaziah, took Joash the son of Ahaziah, and stole him from among the king's sons which were slain; and they hid him, even him and his nurse, in the bedchamber from Athaliah, so that he was not slain.
