Mormon 1:1-4 – Mormon to Receive the Records
1 And now I, Mormon, make a record of the things which I have both seen and heard, and call it the Book of Mormon.
2 And about the time that Ammaron hid up the records unto the Lord, he came unto me, (I being about ten years of age, and I began to be learned somewhat after the manner of the learning of my people) and Ammaron said unto me: I perceive that thou art a sober child, and art quick to observe;
3 Therefore, when ye are about twenty and four years old I would that ye should remember the things that ye have observed concerning this people; and when ye are of that age go to the land Antum, unto a hill which shall be called Shim; and there have I deposited unto the Lord all the sacred engravings concerning this people.
4 And behold, ye shall take the plates of Nephi unto yourself, and the remainder shall ye leave in the place where they are; and ye shall engrave on the plates of Nephi all the things that ye have observed concerning this people.
