Matthew 12:31-32 King James Version (KJV)
31 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.
32 And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
Matthew 12:31-32 Amplified Bible, Classic Edition (AMPC)
31 Therefore I tell you, every sin and blasphemy (every evil, abusive, [a]injurious speaking, or indignity against sacred things) can be forgiven men, but blasphemy against the [Holy] Spirit shall not and [b]cannot be forgiven.
32 And whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Spirit, the Holy One, will not be forgiven, either in this world and age or in the world and age to come.
