room (Some words not found in UHB: and,they_fled [those,who]_remained to,Aphek to/towards the=city and,it_fell the,wall on/upon/above/on_account_of//he/it_went_in twenty and=seven thousand (a)_man [who],remained and,Ben- -hₐdad fled and,he_went to/towards the=city room in,a_room )

The phrase a chamber in a chamber describes an inner room within another room, likely referring to the most secluded or private area of a building. If your readers would not be familiar with rooms that have other rooms inside them, you could use a more general term or explain the arrangement in a footnote. Alternate translation: [an inner room] or [a private room]
