Matthew 5:17-20 New Revised Standard Version (NRSV)
The Law and the Prophets
17 “Do not think that I have come to abolish the law or the prophets; I have come not to abolish but to fulfill. 18 For truly I tell you, until heaven and earth pass away, not one letter,[a] not one stroke of a letter, will pass from the law until all is accomplished. 19 Therefore, whoever breaks[b] one of the least of these commandments, and teaches others to do the same, will be called least in the kingdom of heaven; but whoever does them and teaches them will be called great in the kingdom of heaven. 20 For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.
