Matthew 5:21-22, 27-28

“You have heard that it was said to the men of old, ‘YOU SHALL NOT MURDER,’ and ‘Whoever murders shall be guilty before the court.’ [Ex 20:13; Deut 5:17; 16:18] But I say to you that everyone who continues to be angry with his brother or harbors malice against him shall be guilty before the court; and whoever speaks [contemptuously and insultingly] to his brother, ‘Raca (You empty-headed idiot)!’ shall be guilty before the supreme court (Sanhedrin); and whoever says, ‘You fool!’ shall be in danger of the fiery hell.

“You have heard that it was said, ‘YOU SHALL NOT COMMIT ADULTERY’; [Ex 20:14; Deut 5:18] but I say to you that everyone who [so much as] looks at a woman with lust for her has already committed adultery with her in his heart.
