First Nephi is the abbreviated title of The First Book of Nephi His Reign and Ministry. It is the first published section of The Book of Mormon: Another Testament of Jesus Christ. The book contains a record of an ancient people during a three decade period from approximately 600 BC (BCE) to approximately 570 BC (BCE). The group, headed by Lehi, traveled across the Arabian Peninsula for approximately eight years. After spending some time on the sea shore, the group constructed a ship according to the Lord's directions and sailed across the ocean to the American continent.
