18 For truly, I say to you, till heaven and earth pass away, not an iota, not a dot, will pass from the law until all is accomplished. 19 Whoever then relaxes one of the least of these commandments and teaches men so, shall be called least in the kingdom of heaven; but he who does them and teaches them shall 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.
21 "You have heard that it was said to the men of old, 'You shall not kill; and whoever kills shall be liable to judgment.' 22 But I say to you that every one who is angry with his brother shall be liable to judgment; whoever insults his brother shall be liable to the council, and whoever says, 'You fool!' shall be liable to the hell of fire. 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 and go; first be reconciled to your brother, and then come and offer your gift. 25 Make friends quickly with your accuser, while you are going with him to court, lest your accuser hand you over to the judge, and the judge to the guard, and you be put in prison;

Commentary on Matthew 5:17-20
(Read Matthew 5:17-20)
Let none suppose that Christ allows his people to trifle with any commands of God's holy law. No sinner partakes of Christ's justifying righteousness, till he repents of his evil deeds. The mercy revealed in the gospel leads the believer to still deeper self-abhorrence. The law is the Christian's rule of duty, and he delights therein. If a man, pretending to be Christ's disciple, encourages himself in any allowed disobedience to the holy law of God, or teaches others to do the same, whatever his station or reputation among men may be, he can be no true disciple. Christ's righteousness, imputed to us by faith alone, is needed by every one that enters the kingdom of grace or of glory; but the new creation of the heart to holiness, produces a thorough change in a man's temper and conduct.
Commentary on Matthew 5:21-26
(Read Matthew 5:21-26)
The Jewish teachers had taught, that nothing except actual murder was forbidden by the sixth commandment. Thus they explained away its spiritual meaning. Christ showed the full meaning of this commandment; according to which we must be judged hereafter, and therefore ought to be ruled now. All rash anger is heart murder. By our brother, here, we are to understand any person, though ever so much below us, for we are all made of one blood. "Raca," is a scornful word, and comes from pride: "Thou fool," is a spiteful word, and comes from hatred. Malicious slanders and censures are poison that kills secretly and slowly. Christ told them that how light soever they made of these sins, they would certainly be called into judgment for them. We ought carefully to preserve Christian love and peace with all our brethren; and if at any time there is a quarrel, we should confess our fault, humble ourselves to our brother, making or offering satisfaction for wrong done in word or deed: and we should do this quickly; because, till this is done, we are unfit for communion with God in holy ordinances. And when we are preparing for any religious exercises, it is good for us to make that an occasion of serious reflection and self-examination. What is here said is very applicable to our being reconciled to God through Christ. While we are alive, we are in the way to his judgement-seat; after death, it will be too late. When we consider the importance of the case, and the uncertainty of life, how needful it is to seek peace with God, without delay!
