NIV
And there was a row of masonry inside them, round about [each of] the four courts, and it was made with hearths for boiling at the bottom of the rows round about.

KJV
The rooms on the top floor had no pillars, as the courts had; so they were smaller in floor space than those on the lower and middle floors.
NIV
For they were in three stories, but did not have pillars as the pillars of the [outer] court; therefore the upper chambers were set back more than the lower and the middle ones from the ground.
AMP
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.
