Matthew 5:21-22

“You have heard that it was said to our people long ago, ‘You must not murder anyone. Anyone who murders another will be judged.’ But I tell you, if you are angry with your brother, you will be judged. And if you say bad things to your brother, you will be judged by the Jewish council. And if you call your brother a fool, then you will be in danger of the fire of hell.
