Peace I leave with you; my peace I give to you. I do not give to you as the world gives. Do not let your hearts be troubled, and do not let them be afraid. (John 14:27)
But I say to you, whoever is angry with his brother will be liable to judgment, and whoever says to his brother, Raqa, will be answerable to the Sanhedrin, and whoever says, ‘You fool,’ will be liable to fiery Gehenna.” Matthew 5:21–22
