And the side-chambers are side-chamber by side-chamber, three and thirty times; and they are entering into the wall -- which the house hath for the side-chambers all round about -- to be taken hold of, and they are not taken hold of by the wall of the house.
And a broad place and a turning place still upwards are to the side-chambers, for the turning round of the house is still upwards all round about the house: therefore the breadth of the house is upwards, and so the lower one goeth up unto the higher by the midst.

And the entry of the side-chambers was toward what was left free, one entry toward the north, and one entry toward the south; and the width of the space left free was five cubits round about.
