Matthew 5:19-22

19Therefore, whoever breaks one of the least of these commands and teaches others to do the same will be called least in the kingdom of heaven. But whoever does and teaches these commands will be called great in the kingdom of heaven.

20For I tell you, unless your righteousness surpasses that of the scribes and Pharisees, you will never get into the kingdom of heaven.

21“You have heard that it was said to our ancestors, Do not murder, and whoever murders will be subject to judgment.

22But I tell you, everyone who is angry with his brother or sister will be subject to judgment. Whoever insults his brother or sister will be subject to the court. Whoever says, ‘You fool!’ will be subject to hellfire.
