The cosmological changes that will affect the earth at the time of Christ’s Second Coming (v. 13) is partially quoted or paraphrased in modern revelation. The Lord says he will “cause the heavens to shake for your good” (D&C 21:6 and 35:24). Therefore, this movement of the earth is apparently for the benefit of the righteous and to the detriment of the wicked. There will be more than the house of Israel gathering, for every man will flee to his own land (v. 14). The patriarchal orders established after the flood (see Genesis 10) will perhaps be part of the restoration of this dispensation.
10 That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him: [Ephesians 1:10]
The addition of the bolded “and” (v. 14) is insignificant. However, the Book of Mormon translation of verse 15 contains some significant retentions. The King James text states, “every one that is found shall be thrust through” instead of the bolded “proud.” The King James text would leave no survivors, while the Book of Mormon limits it to the proud. Also, the King James text says “every one that is joined unto them,” rather than joined “to the wicked.” The italics are in the King James text shows that the words were placed there by the translators to make it read better. The Book of Mormon retentions point to a Second Coming prophecy. However, beginning with verse 14, Isaiah seems to describe the literal conquest of Babylon by the Medes. Thus, it appears to be a dual prophecy including spiritual Babylon.
