Luke 12:8-12

Also I say unto you, Whosoever shall confess me before men, him shall the Son of man also confess before the angels of God:

But he that denieth me before men shall be denied before the angels of God.

And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven.

And when they bring you unto the synagogues, and unto magistrates, and powers, take ye no thought how or what thing ye shall answer, or what ye shall say:

For the Holy Ghost shall teach you in the same hour what ye ought to say.
