Gentiles, is, that in the latter days, when our seed shall have
dwindled in unbelief, yea, for the space of many years, and many
generations after the Messiah shall be manifested in body unto
the children of men, then shall the fulness of the gospel of the
Messiah come unto the Gentiles, and from the Gentiles unto the
remnant of our seed--

1 Nephi 15:14
14 And at that day shall the remnant of our seed know that they
are of the house of Israel, and that they are the covenant people
of the Lord; and then shall they know and come to the knowledge
of their forefathers, and also to the knowledge of the gospel of
their Redeemer, which was ministered unto their fathers by him;
wherefore, they shall come to the knowledge of their Redeemer and
the very points of his doctrine, that they may know how to come
unto him and be saved.

1 Nephi 15:15
15 And then at that day will they not rejoice and give praise
unto their everlasting God, their rock and their salvation? Yea,
at that day, will they not receive the strength and nourishment
from the true vine? Yea, will they not come unto the true fold of
God?

1 Nephi 15:16
16 Behold, I say unto you, Yea; they shall be remembered again
among the house of Israel; they shall be grafted in, being a
natural branch of the olive-tree, into the true olive-tree.

1 Nephi 15:17
