When the Gentiles reject the gospel, the word of the Lord will be taken from them and given back to the house of Israel (see vv. 10–12). If the Gentiles then repent and return unto the Lord, “behold they shall be numbered among my people, O house of Israel” (v. 13). Should the Gentiles continue to reject the covenant, however, they will be trodden down and cast out from the promised blessings (see v. 15).
It should be remembered that the Book of Mormon uses the title Gentile in a special way (see student manual commentary on 1 Nephi 13:1–3).
