Matthew 5:22-24

22But 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.

23So then, if you bring your gift to the altar and there remember that your brother has something against you,

24leave your gift there in front of the altar. First go and be reconciled to your brother and then come and present your gift.
