'Bedchamber' in the Bible

When they had come [into] the house, he [was] lying on his couch {in his bedchamber}, and they attacked him and killed him. Then they {beheaded him}, and they took his head and went on the way of the Arabah all night.

Then one of his servants said, "No, my lord the king, but Elisha the prophet who is [in] Israel tells the king of Israel things which you speak {in your own bedchamber}."
