“The door for the middle side rooms was in the right side of the house. They went up by winding stairs into the middle floor, and out of the middle into the third.”
1 Kings 6:8 (WEB)
Context Reading
6The lowest floor was five cubits wide, and the middle was six cubits wide, and the third was seven cubits wide; for on the outside he made offsets in the wall of the house all around, that the beams should not be inserted into the walls of the house. 7The house, when it was under construction, was built of stone prepared at the quarry; and no hammer or ax or any tool of iron was heard in the house while it was under construction. 8The door for the middle side rooms was in the right side of the house. They went up by winding stairs into the middle floor, and out of the middle into the third. 9So he built the house and finished it; and he covered the house with beams and planks of cedar. 10He built the floors all along the house, each five cubits high; and they rested on the house with timbers of cedar.
