'Foundation' in the Bible

And this was Solomon's foundation for the construction of the house of God. The length by cubits after the first measure was sixty cubits, and the breadth twenty cubits.

And all the work of Solomon was prepared, to the day of the foundation of the house of Jehovah and to its completion. So the house of Jehovah was finished.

and a third part shall be at the king's house; and a third part at the gate of the foundation; and all the people shall be in the courts of the house of Jehovah.
