Luke 12:10

Amplified Bible

And everyone who speaks a word against the Son of Man, it will be forgiven him; but he who blasphemes against the Holy Spirit [that is, whoever intentionally discredits the Holy Spirit by attributing the authenticating miracles done by Me to Satan], it will not be forgiven him [for him there is no forgiveness]. [Matt 12:31; Mark 3:28-30]
