1 Kings 6:7-8

7While it was being built, the house was built of stone prepared and finished (precut) at the quarry, and no hammer, axe, or iron tool of any kind was heard in the house while it was under construction.

8The entrance to the lowest side chamber was on the right [or south] side of the house; and they would go up winding stairs to the middle [level], and from the middle to the third.
