For they were arranged in three stories, and unlike the courts, they had no pillars. So the upper chambers were set back further than the lower and middle floors.
KJV
For they [were] in three [stories], but had not pillars as the pillars of the courts: therefore [the building] was straitened more than the lowest and the middlemost from the ground.
ASV
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.
