18 For verily I say unto you, Until the heaven and the earth pass away, one iota or one tittle shall in no wise pass from the law till all come to pass. 19 Whosoever then shall do away with one of these least commandments, and shall teach men so, shall be called least in the kingdom of the heavens; but whosoever shall practise and teach [them], he shall be called great in the kingdom of the heavens. 20 For I say unto you, that unless your righteousness surpass [that] of the scribes and Pharisees, ye shall in no wise enter into the kingdom of the heavens.

Jesus' Attitude toward Anger

21 Ye have heard that it was said to the ancients, Thou shalt not kill; but whosoever shall kill shall be subject to the judgment. 22 But I say unto you, that every one that is lightly angry with his brother shall be subject to the judgment; but whosoever shall say to his brother, Raca, shall be subject to [be called before] the sanhedrim; but whosoever shall say, Fool, shall be subject to the penalty of the hell of fire. 23 If therefore thou shouldest offer thy gift at the altar, and there shouldest remember that thy brother has something against thee, 24 leave there thy gift before the altar, and first go, be reconciled to thy brother, and then come and offer thy gift. 25 Make friends with thine adverse party quickly, whilst thou art in the way with him; lest some time the adverse party deliver thee to the judge, and the judge deliver thee to the officer, and thou 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!
