Mark 3:28 in the King James Version
Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme:
Context
27 But no one can enter into the house of the strong man to plunder unless he first binds the strong man; then he will plunder his house.
28 “Most certainly I tell you, all sins of the descendants of man will be forgiven, including their blasphemies with which they may blaspheme;
29 but whoever may blaspheme against the Holy Spirit never has forgiveness, but is subject to eternal condemnation.”
