Seriously, dude? You have read the Bible I hope. Mt 5:38-48. Whenever Jesus says, "You have heard that..." and then says, "But I say..." he is refuting the OT.
Jesus is not refuting the Old Testament. He stated plainly in (Matt. 5:17), "Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill."
Jesus Christ came preaching the 'Kingdom of Heaven', just as John the Baptist did. (Matt. 3:1-2), (Matt. 4:17) Just as He later sent the disciples out to preach. (Matt. 10:7)
That Kingdom will be the one where Jesus is present on earth and ruling in Jerusalem.
In (Matt. 5-7) Jesus is giving the laws of the Kingdom. And they are different then the Mosaic Law. In fact, they are more strict then the Mosaic Law. Under the law you could not commit adultery. Under the Kingdom law, you can not even lust after a woman. (Matt. 5:27-28) Under the law you must perform your oaths. Under Kingdom law you don't even make an oath. (Matt. 5:33-34)
Different set of laws for a different time. Jesus was ready to establish that Kingdom and the laws of it. But He the King was rejected, and the Kingdom didn't come.
