1 Kings 6:3-6

3The vestibule in front of the nave of the house was twenty cubits long, equal to the width of the house, and ten cubits deep in front of the house.

4And he made for the house windows with recessed frames.

5He also built a structure against the wall of the house, running around the walls of the house, both the nave and the inner sanctuary. And he made side chambers all around.

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.
