I Kings 6:1-6

And it came to pass in the four hundred and eightieth year after the children of Israel had come out of the land of Egypt, in the fourth year of Solomon’s reign over Israel, in the month of Ziv, which is the second month, that he began to build the house of the LORD. Now the house which King Solomon built for the LORD, its length was sixty cubits, its width twenty, and its height thirty cubits. The vestibule in front of the sanctuary of the house was twenty cubits long across the width of the house, and the width of the vestibule extended ten cubits from the front of the house. And he made for the house windows with beveled frames. Against the wall of the temple he built chambers all around, against the walls of the temple, all around the sanctuary and the inner sanctuary. Thus he made side chambers all around it. The lowest chamber was five cubits wide, the middle was six cubits wide, and the third was seven cubits wide; for he made narrow ledges around the outside of the temple, so that the support beams would not be fastened into the walls of the temple.
