1st half of Testimony of Joseph Smith (about the coming forth of the Book of Mormon)

And when ye shall receive these things, I would exhort you that ye would ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, wiht real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost. And by the power of the Holy Ghost ye may know the truth of all things.

The first half of the testimony:

-Joseph was praying, and during his prayer the light appeared.

-Moroni appears in the light. He describes Moroni as wearing an extremely white robe and having a glorious countenance.

-Moroni called Joseph by name, introduced himself as a messenger from God, said that God had a work for him to do (a work which would have the world speaking both good and bad of him), tells him about the gold plates which give an account of the former inhabitants of the Americas and contain the fullness of the Gospel "as delivered by the Savior to the ancient inhabitants," and told him of the breastplate, silver bows, and urim and thummim which would be used to translate the plates (as seers).
