S. Matthew 5:22-23, 25-26

but I say unto you, that every one who is angry with his brother shall be in danger of the judgement; and whosoever shall say to his brother, Raca, shall be in danger of the council; and whosoever shall say, Thou fool, shall be in danger of the hell of fire. If therefore thou art offering thy gift at the altar, and there rememberest that thy brother hath aught against thee

Agree with thine adversary quickly, whiles thou art with him in the way; lest haply the adversary deliver thee to the judge, and the judge deliver thee to the officer, and thou be cast into prison. Verily I say unto thee, Thou shalt by no means come out thence, till thou have paid the last farthing.
