Mateus 5

19 Whoever 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 whoever shall do and teach them, the same shall be called great in the kingdom of heaven.

20 For I say to you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, you shall in no case enter into the kingdom of heaven.
