(Isa. 14:1–3; 2 Ne. 6:6–7; 10:8–9)
The Lord’s mercy will be shown by his gathering his people back to their own land. The strangers who will be joined with them are most probably the Gentiles who will have accepted the gospel while the house of Israel is being gathered. The second verse in the Book of Mormon contains an eighteen-word retention which emphasizes the extent of the gathering of Israel—from “the ends of the earth”—and establishes that there will be more than one land for the gathering …
Verse 2 also shows a reversal of the ruling class: whereas Israel had been captive and in bondage to the Gentiles, the Israelites will now rule (in righteousness) over their former oppressors. Verse 3 retains the wording “that day” instead of KJV “the day,” clearly designating the time when Israel will be gathered and freed from bondage.

These verses were fulfilled when Cyrus the Great of Persia issued an order allowing all captive people in Babylon to return to their place of origin. The first group of Jews returned in 538 b.c. and started to rebuild Jerusalem and Judea. Another great exodus of Jews began in 520 b.c., and the group eventually was able to rebuild the walls of Jerusalem, the city itself, and the temple. Later, under the Maccabees (167–70 b.c.), the Jews enjoyed autonomy and prosperity, being so successful that they began to proselyte other people in the area and to grow in numbers. Indeed, the body of Jews grew into the millions by the time of Christ; while Babylon became desolate, Judea flourished… .
These verses can also find two fulfillments in the latter days. First, they may refer to The Church of Jesus Christ of Latter-day Saints, whose missionary work spreads to all nations and prepares for the peaceful conditions under which the Savior will establish his kingdom at the time of his second coming. Second, these verses may refer to the modern-day return of the Jews to the Holy Land and their building of the modern state of Israel. However, the full blessings of these verses will not be realized until the second coming of Christ, when the Jews will accept him as their Savior.
