1 Nephi 13:23

And he said:

Behold it proceedeth out of the mouth of a Jew.

And I, Nephi, beheld it;

and he said unto me:

The book that thou beholdest is a record of the Jews,

which contains the covenants of the Lord,

which he hath made unto the house of Israel;

and it also containeth many of the prophecies of the holy prophets;

and it is a record like unto the engravings

which are upon the plates of brass,

save there are not so many;

nevertheless, they contain the covenants of the Lord,

which he hath made unto the house of Israel;

wherefore, they are of great worth unto the Gentiles.

wherefore, they are of great worth unto the Gentiles.
