1 Kings 6:1-6

Now it came about in the four hundred and eightieth year after the Israelites came out of the land of Egypt, in the fourth year of Solomon’s reign over Israel, in the month of Ziv (April-May) which is the second month, that he began to build the Lord’s house (temple). The length of the house which King Solomon built for the LORD was sixty cubits (90 ft.), its width twenty (30 ft.), and its height thirty cubits (45 ft.). The porch in front of the main room of the house (temple) was twenty cubits long, corresponding to the width of the house, and its depth in front of the house was ten cubits. He also made framed (artistic) window openings for the house. Against the wall of the house he built extensions around the walls of the house, around both the main room (Holy Place) and the Holy of Holies; and he made side chambers all around. The lowest story was five cubits wide, the middle was six cubits wide, and the third was seven cubits wide; for he made offsets (niches) in the walls all around on the outside of the house so that the supporting beams would not be inserted into the walls of the house.
