Matthew 5:22

But I say to you that everyone who continues to be angry with his brother or harbors malice (enmity of heart) against him shall be liable to and unable to escape the punishment imposed by the court; and whoever speaks contemptuously and insultingly to his brother shall be liable to and unable to escape the punishment imposed by the Sanhedrin, and whoever says, You cursed fool! [You empty-headed idiot!] shall be liable to and unable to escape the hell (Gehenna) of fire.
