18 For most certainly, I tell you, until heaven and earth pass away, not even one smallest letter [1] or one tiny pen stroke [2] shall in any way pass away from the law, until all things are accomplished. 19 Whoever, therefore, shall break one of these least commandments, and teach others to do so, shall be called least in the Kingdom of Heaven; but whoever shall do and teach them shall be called great in the Kingdom of Heaven. 20 For I tell you that unless your righteousness exceeds that of the scribes and Pharisees, there is no way you will enter into the Kingdom of Heaven.

Jesus' Attitude toward Anger

21 “You have heard that it was said to the ancient ones, ‘You shall not murder;’ [3] and ‘Whoever shall murder shall be in danger of the judgment.’ 22 But I tell you, that everyone who is angry with his brother without a cause [4] shall be in danger of the judgment; and whoever shall say to his brother, ‘Raca [5]!’ shall be in danger of the council; and whoever shall say, ‘You fool!’ shall be in danger of the fire of Gehenna. [6] 23 “If therefore you are offering your gift at the altar, and there remember that your brother has anything against you, 24 leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift. 25 Agree with your adversary quickly, while you are with him in the way; lest perhaps the prosecutor deliver you to the judge, and the judge deliver you to the officer, and you be cast into prison.

Matthew Henry's Commentary on Matthew 5:18-25

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!
