The First Book of Nephi: His Reign and Ministry (/ˈniːfaɪ/), often referred to simply as First Nephi, is the first book of the Book of Mormon and one of four books with the name Nephi. The original translation of the title did not include the word "first". First and Second were added to the titles of The Books of Nephi by Oliver Cowdery when preparing the book for printing. It is a first-person narrative by a prophet named Nephi, of events that began around 600 BC and recorded on the small plates of Nephi approximately 30 years later. Its 22 chapters tell the story of one family's challenges and the miracles they witness as they escape from Jerusalem, struggle to survive in the wilderness, build a ship and sail to the Americas. The book is composed of two intermingled genres; one a historical narrative describing the events and conversations that occurred and the other a recording of visions, sermons, poetry, and doctrinal discourses as shared by either Nephi or Lehi to members of the family.
The Second Book of Nephi is a continuation of this narrative and immediately follows this book.
Beginning in Jerusalem at the time of King Zedekiah, Nephi's father Lehi, has a vision and is warned of the imminent Babylonian destruction of Jerusalem. Lehi attempts to share this warning with the people of Jerusalem, but they reject him and try to kill him. Lehi and his family (wife Sariah, four sons Laman, Lemuel, Sam, and Nephi, and unnamed daughters) leave Jerusalem and establish a camp in the wilderness. Lehi preaches to his family, especially Laman and Lemuel who do not believe their father's vision and complained about the wealth and comforts they left behind. After praying, Nephi is convinced of his father's words and inspires his older brother Sam to also believe. As Nephi prays, the Lord promises that he will be a "ruler and a teacher" over his brothers, so long as he is faithful and they continue to rebel.
