21 "You're familiar with the command to the ancients, 'Do not murder.' 22 I'm telling you that anyone who is so much as angry with a brother or sister is guilty of murder. Carelessly call a brother 'idiot!' and you just might find yourself hauled into court. Thoughtlessly yell 'stupid!' at a sister and you are on the brink of hellfire. The simple moral fact is that words kill. 23 "This is how I want you to conduct yourself in these matters. If you enter your place of worship and, about to make an offering, you suddenly remember a grudge a friend has against you, 24 abandon your offering, leave immediately, go to this friend and make things right. Then and only then, come back and work things out with God. 25 "Or say you're out on the street and an old enemy accosts you. Don't lose a minute. Make the first move; make things right with him. After all, if you leave the first move to him, knowing his track record, you're likely to end up in court, maybe even jail.

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!
