The Sealed Portion

Church Educational System
A portion of the plates from which Joseph Smith translated the Book of Mormon was sealed, and he was commanded not to translate that part. Nephi wrote of what was contained in the sealed portion (see 2 Nephi 27:7, 10), when it would become available to us (see v. 10; see also Ether 4:4–7), and how it would be made available (see 2 Nephi 27:11). The verses in 1 Nephi 14:26 and 3 Nephi 26:9–11 also refer to the sealing up of sacred writings.
