Matthew 5:19-21 Holman Christian Standard Bible (HCSB)
19 Therefore, whoever breaks one of the least of these commands and teaches people to do so will be called least in the kingdom of heaven. But whoever practices and teaches these commands will be called great in the kingdom of heaven. 20 For I tell you, unless your righteousness surpasses that of the scribes and Pharisees, you will never enter the kingdom of heaven.
