Melachim Alef 6:7-9

Orthodox Jewish Bible

⁷ And the Beis [Hamikdash], when it was under construction, was built of stone made ready before it was brought there; so was neither hammer nor chisel nor any tool of iron heard in the Beis [Hamikdash], while it was under construction.

⁸ The door for the middle story was in the right side of the Beis [Hamikdash]; and they went up with winding stairs into the middle chamber, and out of the middle into the third.

⁹ So he built the Beis [Hamikdash], and finished it; and covered the Beis [Hamikdash] with beams and boards of cedar.
