'Foundation stone' in the Bible
And so Solomon completed all of the work, from the day that the foundation stone of the LORD's Temple was laid until the LORD's Temple was completely finished.
Let the Temple be rebuilt where they offered sacrifices. Let the foundations thereof be laid with a height of 60 cubits and a width of 60 cubits, constructed with three layers of foundation stone interlaced with a row of new timber, the expenses for which are to be paid from the king's treasury.
therefore this is what the LORD God says: "Look! I am laying a foundation stone in Zion, a tested stone, a precious cornerstone for a sure foundation: Whoever believes firmly will not act hastily.
They won't get a cornerstone or a foundation stone from you, because you will be a wasteland forever," declares the LORD.
