Matthew 5:19-22

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.

21Ye have heard that it was said to the ancients, Thou shalt not kill; but whosoever shall kill shall be subject to the judgment.

22But I say unto you, that every one that is lightly angry with his brother shall be subject to the judgment; but whosoever shall say to his brother, Raca, shall be subject to [be called before] the sanhedrim; but whosoever shall say, Fool, shall be subject to the penalty of the hell of fire.
