Summer-house
Am 3:15 notes it as part of the judgment on Israel that Yahweh would smite "the winter-house with the summer-house." It belonged to the luxury of the period that kings and wealthy persons had separate residences for the cold and hot seasons. This is the only mention of "the summer-house," but Eglon’s "cool upper room" (Jud 3:20, the King James Version and the English Revised Version "summer parlour," not in this case a separate building) may be compared.
