1 Nephi 5:17–19

17 And now when my father saw all these things, he was filled with the Spirit, and began to prophesy concerning his seed—

18 That these plates of brass should go forth unto all nations, kindreds, tongues, and people who were of his seed.

19 Wherefore, he said that these plates of brass should never perish; neither should they be dimmed any more by time. And he prophesied many things concerning his seed.

Lehi makes an interesting prophecy about the brass plates going to “all nations, kindreds, tongues, and people who were of his seed.” I believe this has reference to the gathering of Israel in the last days. Lehi’s descendants probably are not the main people of every nation on earth, nor are they the only ones receiving the Book of Mormon, which contains the record of the brass plates. But that is not what Lehi said in his prophecy, or at least I can see a different understanding. Lehi is of the seed of Joseph, which he discovered from the plates. Probably about 95% of people who get their patriarchal blessings are of the tribe of Joseph, mostly Ephraim. Those who receive their patriarchal blessings are members of the Church who have received the Book of Mormon. This verse could also refer to how Lehi’s descendants who may be found throughout the world will accept the Book.
