The Bible, Taxes, and Urine?

The Bible contains a number of "tax" related passages including Matthew 22:16-22 in which Jesus referred to a denarius and famously said, "render to Caesar the things that are Caesar's, and to God the things that are God's." One can be thankful that our Lord used a coin and not some other things that have been taxed throughout history, including urine. See this article in National Geographic.
