1 Kings 6:8-17

The entrance for the lowest story was on the south side of the house, and one went up by stairs to the middle story, and from the middle story to the third. So he built the house and finished it, and he made the ceiling of the house of beams and planks of cedar. He built the structure against the whole house, five cubits high, and it was joined to the house with timbers of cedar. Now the word of the LORD came to Solomon, “Concerning this house that you are building, if you will walk in my statutes and obey my rules and keep all my commandments and walk in them, then I will establish my word with you, which I spoke to David your father. And I will dwell among the children of Israel and will not forsake my people Israel.” So Solomon built the house and finished it. He lined the walls of the house on the inside with boards of cedar. From the floor of the house to the walls of the ceiling, he covered them on the inside with wood, and he covered the floor of the house with boards of cypress. He built twenty cubits of the rear of the house with boards of cedar from the floor to the walls, and he built this within as an inner sanctuary, as the Most Holy Place. The house, that is, the nave in front of the inner sanctuary, was forty cubits long.
