1 Kings 6:7-8

71The house, while it was being built, was built of stone finished at the quarry, and neither hammer, nor axe, nor any iron tool was heard in the house while it was being built.

8The doorway for the 2lowest side chamber was on the right side of the house; and they would go up by a winding staircase to the middle story, and from the middle to the third.
