The Lord “committed the keys of the record of the stick of Ephraim” to Moroni (D&C 27:5). He thus became the principal figure in the transmission of the record to this dispensation as well as the protector of the record itself. Moroni was “the last Nephite prophet in the Book of Mormon (circa A.D. 421). Just before Mormon’s death, he delivered a historical record called the plates of Mormon to his son Moroni (W of M 1:1). Moroni finished compiling the plates of Mormon. He added chapters 8 and 9 to the book of Mormon (Morm. 8:1). He abridged and included the book of Ether (Ether 1:1–2) and added his own book called the book of Moroni (Moro. 1:1–4). Moroni sealed up the plates and hid them in the hill Cumorah (Morm. 8:14; Moro. 10:2). In 1823 Moroni was sent as a resurrected being to reveal the Book of Mormon to Joseph Smith (JS—H 1:30–42, 45; D&C 27:5). He instructed the young prophet each year from 1823 to 1827 (JS—H 1:54) and finally delivered the plates to him in 1827 (JS—H 1:59). After completing the translation Joseph Smith returned the plates to Moroni” (Guide to the Scriptures, “Moroni, Son of Mormon”).
