Matthew 5:19-22

19So if you ignore the least commandment and teach others to do the same, you will be called the least in the Kingdom of Heaven. But anyone who obeys God’s laws and teaches them will be called great in the Kingdom of Heaven.

20“But I warn you—unless your righteousness is better than the righteousness of the teachers of religious law and the Pharisees, you will never enter the Kingdom of Heaven!

21“You have heard that our ancestors were told, ‘You must not murder. If you commit murder, you are subject to judgment.’

22But I say, if you are even angry with someone, you are subject to judgment! If you call someone an idiot, you are in danger of being brought before the court. And if you curse someone, you are in danger of the fires of hell.
