Biblical Foundation of Our Government Structure

It's common knowledge that the founders of the United States were heavily influenced by the Bible (as well as other sources). But this really came home to me the other night as I was reading Isaiah 33:22:

For YHWH is our Judge,
YHWH is our lawgiver,
YHWH is our King.
He will save us.

There's our three branches of government in the first three lines: Judicial, Legislative, and Executive.

Cool!

The last line has also been pre-empted by modern minds; we tend to think that the U.S. Government will save us.
