What are some Bible verses that address the concept of separation of church and state?

The concept of separation of church and state is not explicitly mentioned in The Bible. However, some verses that are often cited in discussions about this concept include Matthew 22:21 ("Render unto Caesar the things that are Caesar's, and unto God the things that are God's") and Romans 13:1 ("Let every person be subject to the governing authorities"). These verses are interpreted by some as supporting the idea of a distinction between religious and governmental authority.
