In 4 Nephi Mormon condensed approximately 285 years of writings and history into four pages, a single chapter of forty-nine verses. The four original writers of the material Mormon abridged were Nephi, the son of Nephi the disciple of Christ, Amos, the son of Nephi, and Amos and Ammaron, the sons of the first Amos (see 4 Nephi 1:19–21, 47–48).
