Matthew 5:22-24

5:22 But I say to you that anyone who is angry with a brother will be subjected to judgment. And whoever insults a brother will be brought before the council, and whoever says ‘Fool’ will be sent to fiery hell. 5:23 So then, if you bring your gift to the altar and there remember that your brother has something against you, 5:24 leave your gift there in front of the altar. First go and be reconciled to your brother and then come and present your gift.
