Matthew 5:17-20

17Think not that I am come to make void the law or the prophets; I am not come to make void, but to fulfil.

18For verily I say unto you, Until the heaven and the earth pass away, one iota or one tittle shall in no wise pass from the law till all come to pass.

19Whosoever then shall do away with one of these least commandments, and shall teach men so, shall be called least in the kingdom of the heavens; but whosoever shall practise and teach [them], he shall be called great in the kingdom of the heavens.

20For I say unto you, that unless your righteousness surpass [that] of the scribes and Pharisees, ye shall in no wise enter into the kingdom of the heavens.
