What Did Jesus Say About Exceeding In Righteousness?

Do not think that I am come to destroy the law or the prophets: I am not come to destroy them but to fulfil.

For verily I say unto you, until heaven and earth shall pass, not one jot or one tittle shall pass from the law until all be fulfilled. Whosoever, therefore, shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.

For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, you shall in no way enter into the kingdom of heaven. Matthew 5 vs 17-20.
