Mateus 5

19 Whoever therefore shall break one of the least of these commandments, and shall teach men thus, will be called least in the kingdom of heaven; but whoever does [them] and teaches [them], he shall be called great in the kingdom of heaven.

20 For I say to you, that unless your righteousness exceeds the righteousness of the scribes and Pharisees, you shall by no means enter the kingdom of heaven.
