The length of the porch was twenty cubits and the width eleven cubits; and at the stairway by which it was ascended, there were [two] columns beside the side pillars, one on each side [of the entrance].

And I saw that the house had a stone floor all round; the bases of the side-rooms were a full rod of six great cubits high.
