Mark 3:28-30 King James Version (KJV)
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.
Mark 3:28-30 Amplified Bible, Classic Edition (AMPC)
28 Truly and solemnly I say to you, all sins will be forgiven the sons of men, and whatever abusive and blasphemous things they utter;
29 But whoever speaks abusively against or maliciously misrepresents the Holy Spirit can never get forgiveness, but is guilty of and is in the grasp of [a]an everlasting trespass.
Mark 3:28-30 Living Bible (TLB)
28 “I solemnly declare that any sin of man can be forgiven, even blasphemy against me; 29 but blasphemy against the Holy Spirit can never be forgiven. It is an eternal sin.”
30 He told them this because they were saying he did his miracles by Satan’s power instead of acknowledging it was by the Holy Spirit’s power.[a]
