The Doctrine and Covenants/Section 32

Revelation through Joseph Smith to Parley P. Pratt and Ziba Peterson, October 1830. History of the Church 1:118-20.

And now concerning my servant Parley P. Pratt, behold, I say unto him that as I live I will that he shall declare my gospel and learn of me, and be meek and lowly of heart.

And that which I have appointed unto him is that he shall go with my servants, Oliver Cowdery and Peter Whitmer, Jun., into the wilderness among the Lamanites.

And Ziba Peterson also shall go with them; and I myself will go with them and be in their midst; and I am their advocate with the Father, and nothing shall prevail against them.

And they shall give heed to that which is written, and pretend to no other revelation; and they shall pray always that I may unfold the same to their understanding.

And they shall give heed unto these words and trifle not, and I will bless them. Amen.
