Mark 3:28-30

Young's Literal Translation

²⁸ `Verily I say to you, that all the sins shall be forgiven to the sons of men, and evil speakings with which they might speak evil,

²⁹ but whoever may speak evil in regard to the Holy Spirit hath not forgiveness -- to the age, but is in danger of age-during judgment;'

³⁰ because they said, `He hath an unclean spirit.'
