The nethermost chamber was five cubits broad, and the middle was six cubits broad, and the third was seven cubits broad: for without in the wall of the house he made narrowed rests round about, that the beams should not be fastened in the walls of the house.
1 Kings 6:6
The floor the lower part, five by the cubit its breadth, and the middle, six by the cubit its breadth, and the third, seven by the cubit its breadth: for he gave offsets to the house round about without, so that it laid not hold upon the walls of the house.
And the chamber one reed the length, and one reed the breadth; and between the chambers, five cubits: and the threshold of the gate from the side of the porch of the gate from the house, one reed.
