What did Jesus say about Blasphemy?

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.”

⁸ “I tell you, everyone who confesses me before men, the Son of Man will also confess before the angels of God;

⁹ but he who denies me in the presence of men will be denied in the presence of God’s angels.

¹⁰ Everyone who speaks a word against the Son of Man will be forgiven, but those who blaspheme against the Holy Spirit will not be forgiven.

¹¹ When they bring you before the synagogues, the rulers, and the authorities, don’t be anxious how or what you will answer or what you will say;

¹² for the Holy Spirit will teach you in that same hour what you must say.”
