Write It

2 Nephi chapter 29:

12 For behold, I shall speak unto the Jews and they shall write it; and I shall also speak unto the Nephites and they shall write it; and I shall also speak unto the other tribes of the house of Israel, which I have led away, and they shall write it; and I shall also speak unto all nations of the earth and they shall write it.

Nephi was very familiar with the writings of the Old Testament, especially regarding to messianic messages.  He cites "write it" four times in verse 29. Of which many were I believe found in the Brass Plates. Nephi was taught by such records.  In fact, Nephi wrote and taught according to biblical verses as referenced in...

Ezekiel 43:11...and write it in their sight, that they may keep the whole form thereof, and all the ordinances thereof, and do them.

Jeremiah 31: But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts and write it in their hearts; and will be their God, and they shall be my people.

Isaiah 30: Now go, write it before them in a table, and note it in a book, that it may be for the time to come for ever and ever.

Nehemiah 9:38 And because of all this we make a sure covenant, and write it; and our princes, Levites, and priests, seal unto it.

Nephi's authenticity and teaching prove appropriate to messianic messages of the covenants from his word's written in the Book of Mormon.
