'Bedchamber' in the Bible

and the river shall swarm with frogs, which shall go up and come into thy house, and into thy bedchamber, and upon thy bed, and into the house of thy servants, and upon thy people, and into thine ovens, and into thy kneading-troughs:

Now when they came into the house, as he lay on his bed in his bedchamber, they smote him, and slew him, and beheaded him, and took his head, and went by the way of the Arabah all night.

And one of his servants said, Nay, 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 away from among the king's sons that were slain, even him and his nurse, and put them in the bedchamber; and they hid him from Athaliah, so that he was not slain;

But Jehoshabeath, the daughter of the king, took Joash the son of Ahaziah, and stole him away from among the king's sons that were slain, and put him and his nurse in the 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.

Revile not the king, no, not in thy thought; and revile not the rich in thy bedchamber: for a bird of the heavens shall carry the voice, and that which hath wings shall tell the matter.
