This feminine noun denotes a cool chamber or upper room designed for comfort in hot weather. Both occurrences appear in Judges 3 during the Ehud narrative. Verse 20 describes Ehud approaching King Eglon 'sitting in his cool roof chamber,' and verse 24 has the servants assuming the king has shut himself in 'the cool chamber' (literally 'covering his feet,' a euphemism). The term suggests an architectural feature—likely an upper room with ventilation or positioning to catch breezes, providing relief from Jordan Valley heat. This private, comfortable space becomes the scene of Eglon's assassination.
