Second Book of Nephi Chapters fourteen and fifteen. Book of Mormon 1830 First Edition.

Nephi shares his last words in chapter 14 and 15, that he cries upon his pillow at night for the people. He shares that we have the voice of an Angel by the Holy Ghost, that we can speak as with the voice of an angel according to the Holy Ghost which shares the words of Christ. Nephi shares that we need to pray always, and to pray before we do things so our actions can be blessed. Nephi is sad at the unbelief and wickedness of men.
