Mormon 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. And about the time that Ammaron hid up the records unto the Lord, he came unto me, I being about ten years of age ā€” and I began to be learned somewhat after the manner of the learning of my people ā€” and Ammaron said unto me, I perceive that thou art a sober child, and art quick to observe. 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.
