'Lowest' in the Bible

The side rooms were broader as they encompassed [the house] higher and higher; for the encompassing of the house went higher and higher around the house: therefore the breadth of the house [continued] upward; and so one went up [from] the lowest [room] to the highest by the middle [room].

For they were in three stories, and they didn't have pillars as the pillars of the courts: therefore [the uppermost] was straitened more than the lowest and the middle from the ground.
