Matthew 5:21-22

“You have heard that it was said by the ancients, ‘You shall not murder,’ and ‘Whoever murders shall be in danger of the judgment.’ But I say to you that whoever is angry with his brother without a cause shall be in danger of the judgment. And whoever says to his brother, ‘Raca,’ shall be in danger of the Sanhedrin. But whoever says, ‘You fool,’ shall be in danger of hell fire.
