'Side chambers' in the Bible

Against the wall of the house he built extensions around the walls of the house, around both the main room (Holy Place) and the Holy of Holies; and he made side chambers all around.

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 it was covered with cedar [as a roof] on the supporting beams that were upon the forty-five pillars, fifteen in each row.

Then he measured the wall of the temple, six cubits [thick, to accommodate side chambers]; and the width of every side chamber, four cubits, all around the temple on every side.

The side chambers were three stories [high], one above another, and thirty chambers in each story; and the side chambers extended to the wall which stood on their inward side all around, so that they would be attached, but not attached to the wall of the temple itself.

I also saw that the temple (house) had a raised platform all around it; the foundations of the side chambers measured a full rod of six long cubits in height.

The thickness of the outer wall of the side chambers was five cubits. But the free space between the side chambers belonging to the temple

The doorways of the side chambers toward the free space were one doorway toward the north and another doorway toward the south; and the width of the free space was five cubits all around.

There were latticed windows and palm decorations on one side and on the other, on the sides of the porch. Thus were the side chambers and the thresholds of the house.
