6The lowest story

was five cubits broad, the middle one was six cubits broad, and the third was seven cubits broad. For around the outside of the house he made offsets on the wall in order that the supporting beams should not be inserted into the walls of the house.

7When the house was built, fit was with stone prepared at the quarry, so that neither hammer nor axe nor any tool of iron was heard in the house while it was being built.

9 hSo he built the house and finished it, and he made the ceiling of the house of beams and planks of cedar. 10He built the structure against the whole house, five cubits high, and it was joined to the house with timbers of cedar.
