1 Kings 6:1-3

Now it came about in the four hundred and eightieth year after the sons of Israel came out of the land of Egypt, in the fourth year of Solomon’s reign over Israel, in the month of Ziv, that is, the second month, that he began to build the house of the Lord.

And the house which King Solomon built for the Lord was sixty cubits in its length, and twenty cubits in its width, and its height was thirty cubits.

The porch in front of the main room of the house was twenty cubits in length, corresponding to the width of the house, and its width along the front of the house was ten cubits.
