Matthew 5:21-24

21 "You have heard that it was said to those of old, 'You shall not murder, and whoever murders will be in danger of the judgment.'

22 But I say to you that whoever is angry with his brother without a cause shall be in danger of the judgment. And whoever says to his brother, 'Raca!' shall be in danger of the council. But whoever says, 'You fool!' shall be in danger of hell fire.

23 Therefore if you bring your gift to the altar, and there remember that your brother has something 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.
