Matthew 5:21-22

21“You have heard that it was said to the people long ago, ‘You shall not murder, and anyone who murders will be subject to judgment.’

22But I tell you that anyone who is angry with a brother or sister will 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.
