But I tell you that anyone who is angry with a brother or sisterwill be subject to judgment. Again, anyone who says to a brother or sister, ‘Raca,’is answerable to the court. And anyone who says, ‘You fool!’ will be in danger of the fire of hell.
References for Matthew 5:22
“Therefore, if you are offering your gift at the altar and there remember that your brother or sister has something against you,
leave your gift there in front of the altar. First go and be reconciled to them; then come and offer your gift.
