17Do not think that I came to destroy the law or the prophets; I did not come to destroy but to fulfill.18For amen I say to you, until heaven and earth pass away, not one iota or one tittle will pass away from the law until all things take place.19Therefore whoever breaks one of the least of these commandments and teaches people accordingly will be called least in the kingdom of the heavens, but whoever does them and teaches them will be called great in the kingdom of the heavens.20For I say to you that unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of the heavens.
