'Chambers' in the Bible

And against the wall of the house he built chambers round about, against the walls of the house round about, both of the temple and of the oracle: and he made chambers round about:

The lowest story was five cubits wide, the middle was six cubits wide, and the third was seven cubits wide; for he made offsets (niches) in the walls all around on the outside of the house so that the supporting beams would not be inserted into the walls of the house.

And then he built chambers against all the house, five cubits high: and they rested on the house with timber of cedar.

It was paneled above with cedar at the top of the chambers that rested on 45 pillars, 15 per row.
