Matthew 5:21

17 Do not think that I have come to abolish the Law or the Prophets. I have not come to abolish them, but to fulfill them.

18 For I tell you truly, until heaven and earth pass away, not a single jot, not a stroke of a pen, will disappear from the Law until everything is accomplished.

19 So then, whoever breaks one of the least of these commandments and teaches others to do likewise will be called least in the kingdom of heaven; but whoever practices and teaches them will be called great in the kingdom of heaven.

20 For I tell you that unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.

21 You have heard that it was said to the ancients, ‘Do not murder’ and ‘Anyone who murders will be subject to judgment.’

22 But I tell you that anyone who is angry with his brother will be subject to judgment. Again, anyone who says to his brother, ‘Raca,’ will be subject to the Sanhedrin. But anyone who says, ‘You fool!’ will be subject to the fire of hell.

23 So if you are offering your gift at the altar and there remember that your brother has something against you,

24 leave your gift there before the altar. First go and be reconciled to your brother; then come and offer your gift.

25 Reconcile quickly with your adversary, while you are still on the way to court. Otherwise, he may hand you over to the judge, and the judge may hand you over to the officer, and you may be thrown into prison.
