19 Whosoever therefore shall undo one of these least commandments and shall teach men so, he shall be called the least in the kingdom of the heavens; but whosoever shall do and teach [them], the same shall be called great in the kingdom of the heavens.20 For I say unto you, That except your righteousness shall exceed [the righteousness] of the scribes and Pharisees, ye shall in no case enter into the kingdom of the heavens.
