Mark 3:28-30

King James Version

²⁸ Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme:

²⁹ But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation.

³⁰ Because they said, He hath an unclean spirit.
