Mark 3:28-30

Diaglott(i) 28 Indeed I say to you, that all will be forgiven to the sons of the men the sins, and the evil speakings, whatever they may revile; 29 who but ever may speak evil to the spirit the holy, not has forgiveness to the age, but liable is of age-lasting judgment. 30 Because they said: A spirit unclean he has.
