'Foundations' in the Bible

So I will tear down the wall which you have plastered with whitewash and bring it down to the ground, so that its foundations will be exposed; when it falls, you will perish in its midst. And you shall know and understand fully that I am the Lord.

“A sword will come upon Egypt,And anguish and trembling will be in Ethiopia (Cush),When the slain fall in EgyptAnd they [of Babylon] carry away her great mass of people and her richesAnd her foundations are torn down.

I also saw that the temple (house) had a raised platform all around it; the foundations of the side chambers measured a full rod of six long cubits in height.
