Matthew 5:22-24

22But I say to you, That whoever is angry with his brother without a cause shall be in danger of the judgment: and whoever shall say to his brother, Raca, shall be in danger of the council: but whoever shall say, Thou fool, shall be in danger of hell fire.1 23Therefore if thou shalt bring thy gift to the altar, and there remember that thy brother hath any thing against thee; 24Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother, and then come and offer thy gift.
