'Foundation' in the Bible

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

and the outer chambers was a width of twenty cubits all around the temple on every side.

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.
