2 Nephi 26:15
1830 Edition
After that my seed and the seed of my brethren shall have dwindled in unbelief, and shall have been smitten by the Gentiles; yea, after that the Lord God shall have camped against them round about, and shall have laid siege against them with a mount, and raised forts against them; and after that they shall have been brought down low into the dust, even that they are not, yet the words of the righteous shall be written, and the prayers of the faithful shall be heard, and all they which have dwindled in unbelief, shall not be forgotten;
Changes
Simple English
After my children and my brothers’ children stop believing and are hurt by the Gentiles, after the Lord God fights against them all around and attacks them and builds forts against them, after they are brought down low into the dust so they are almost gone, the words of the righteous will still be written. The prayers of the faithful will still be heard. All who stopped believing will not be forgotten.
Paraphrase
After my descendants and my brothers' descendants have fallen into unbelief and been struck down by the Gentiles—after the Lord God has besieged them with armies, built siege ramps against them, and raised forts around them—after they’ve been brought down so low in the dust that they seem to be nothing—even then, the words of the righteous will be written down, and the prayers of the faithful will be heard. All those who have fallen into unbelief will not be forgotten.
Notes
The phrase, "dwindled in unbelief" can be found in 2 Nephi 26:15; Helaman 15:11, Ether 4:3, D&C 3:18.
"After noticing that the same phrases of two or more words appear time after time throughout Joseph Smith's scriptures, we did a computer search to identify these groups of words and feel that they provide evidence that the Book of Mormon, the Inspired Version of the Bible, the Doctrine and Covenants and the Pearl of Great Price were all the product of one mind.... When we find a number of different Book of Mormon writers-e.g., Nephi, Jacob, Enos, Moroni and Mormon-all using many of the same unusual word combinations, we begin to suspect that all these books were actually written by one person."-Jerald and Sandra Tanner, Joseph Smith's Plagiarism of the Bible in the Book of Mormon, p. 39.
Other common phrases include "expedient that" (2 Nephi 9:15; Alma 34:9; Mosiah 13:27; D&C 9:3), "it must needs be" (1 Nephi 15:33; Alma 32:28; 3 Nephi 5:1; D&C 48:3), "save it were" (Helaman 3:23; 4 Nephi 1:5; D&C 18:35), "sufficeth me" (2 Nephi 11:1; Jarom 1:2; Ether 3:17), "would that ye should" (Alma 38:5; Mosiah 1:3; Omni 1:2; D7C 46:7).
