'Side chambers' in the Bible

And the side-chambers were three, one over another, and thirty in order; and they entered into the wall which was of the house for the side-chambers around, that they might have hold, but they had not hold in the wall of the house.

And there was an enlarging, and a winding about still upward to the side-chambers: for the winding about of the house went still upward around the house; therefore the breadth of the house was still upward, and so increased from the lowest chamber to the highest by the midst.

I saw also the hight of the house around: the foundations of the side-chambers were a full reed of six great cubits.

The thickness of the wall, which was for the side-chamber without, was five cubits: and that which was left was the place of the side-chambers that were within.

And the doors of the side-chambers were towards the place that was left, one door towards the north, and another door towards the south: and the breadth of the place that was left was five cubits around.

And there were narrow windows and palm-trees on the one side and on the other side, on the sides of the porch, and upon the side-chambers of the house, and thick planks.
