You say that Jesus was expanding on the Law, exposing the true standard to make the rich man sad and the Pharisees mad. Where can I find verses clearly showing he’s expanding on the Law?
“You have heard that it was said, ‘Do not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. If your right eye causes you to sin, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell.
“You have heard that it was said to the people long ago, ‘Do not murder, and anyone who murders will be subject to judgment.’ But I tell you that anyone who is angry with his brother will be subject to judgment.
