Verses 22–25 continue to refer to the Gentiles. After discussing the fate of the unbelieving Gentiles, Jesus turns to the faithful Gentiles. They will be those who assist in the gathering. They will assist as the united house of Israel builds a New Jerusalem, which is a symbolic center for the New World gathered, just as the Jerusalem in the Old World serves as the symbolic center for the house of Israel in the Old World.
This assistance reprises Isaiah 49:22–23: “Thus saith the Lord God, Behold, I will lift up mine hand to the Gentiles, and set up my standard to the people: and they shall bring thy sons in their arms, and thy daughters shall be carried upon their shoulders. And kings shall be thy nursing fathers, and their queens thy nursing mothers: they shall bow down to thee with their face toward the earth, and lick up the dust of thy feet; and thou shalt know that I am the Lord: for they shall not be ashamed that wait for me.”
Nephi (son of Lehi) and his brother Jacob both quoted these verses with the emphasis on the way the Gentiles would aid the house of Israel (see 1 Nephi 21:22–23, and 2 Nephi 6:6–7 where Jacob is teaching). Thus, this allusion also serves to underscore what Nephi and Jacob taught.
