'Space' in the Bible

The lowest line of them being five cubits wide, the middle six cubits wide and the third seven cubits; for there was a space all round the outside walls of the house so that the boards supporting the rooms did not have to be fixed in the walls of the house.

And at the back of the house a further space of twenty cubits was shut in with boards of cedar-wood, for the inmost room.

And the inner space was walled with three lines of squared stones and a line of cedar-wood boards.
