Sealed book of Mormon Ch.21

AND now I, Moroni, am again constrained
by the Spirit to write unto you concerning the
manner in which these things are written
upon the plates which I have made with my
own hands.
And I have seen the day that these things
shall come unto you. And there shall be many
in that day who shall mock these things, and
also him by whom these things shall be given
unto you. And many of you shall think that
these things were copied from the writings of
others who have come before us.
And I have also seen many of the scriptures
which shall come forth unto you. And many of
the things that are written upon these plates shall
be similar to, if not in the exact likeness of many
of those things that have been written by the
hand of other prophets of God.
And this is the will and the command of the
Lord concerning all things that shall be written.
For if a man hath the spirit of prophecy, then he
shall write the same words, in the same likeness,
of all those who have been given this spirit of
prophecy by the Lord. And this spirit of
prophecy is a gift given unto a chosen vessel
who hath been preordained and chosen by the
Lord to do the thing that shall be required of him.
