"28Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme: 29But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation: 30Because they said, He hath an unclean spirit."

"I said, Master, where will the souls go of people who had knowledge but turned away?
He said to me, They will be taken to the place where the angels of misery go, where there is no repentance. They will be kept there until the day when those who have blasphemed against the spirit will be tortured and punished eternally."
