'Private' in the Bible

Then Micaiah said, "Behold, you will see on that day when you go into a private room to hide yourself."

But Jehosheba the daughter of the king took Joash, the son of Ahaziah, and kidnapped him away from the sons of the king who were to be put to death. And she put him and his nurse in a private bedroom. So Jehosheba the daughter of King Jehoram, the wife of Jehoiada the priest, because she was a sister of Ahaziah, hid him from before Athaliah so that she did not put him to death.
