International Standard Version The three part structure had no columns, unlike the courts, which is why the upper chambers were offset from the ground upward, more so than the lower and middle chambers.
American Standard Version For they were in three stories, and they had not pillars as the pillars of the courts: therefore the uppermost was straitened more than the lowest and the middlemost from the ground.
Young's Literal Translation for they are threefold, and they have no pillars as the pillars of the court, therefore it hath been kept back -- more than the lower and than the middle one -- from the ground.
