Matthew 5:20-22

20I tell you this: You must always do what is right. You must live in a way that is better than the teachers of God's Law and the Pharisees. You will never come into the kingdom of heaven if you do not do better than them.’

21Jesus then said, ‘You know the rule that God gave to your ancestors: “You must not kill anyone. Any person who does kill someone will stand in front of a judge. The judge will punish him because he has done a wrong thing.”

22But what I now say to you is this: Anybody who is angry with his brother will have to stand in front of a judge. Or someone might call his brother by a bad name. Then he will have to stand in front of the Jewish leaders. They will judge him. But someone may say to his brother, “You are a fool.” God will judge that person. God may punish him in the fires of hell.
