'Apartment' in the Bible

Ehud came to him as he was sitting alone in his [private] cool upper chamber, and Ehud said, “I have a message from God for you.” And the king got up from his seat.

Ezra arose in front of the Temple of God to visit the apartment of Eliashib's son Jehohanan. While there, he neither ate nor drank because he was in mourning over the sins of those who had returned from exile.

Now the young woman pleased Hegai and found favor with him. So he quickly provided her with beauty preparations and her [portion of] food, and he gave her seven choice maids from the king’s palace; then he transferred her and her maids to the best place in the harem.
