Alma 18:37-38

37 And he also rehearsed unto them (for it was unto the king and to his servants) all the journeyings of their fathers in the wilderness, and all their sufferings with hunger and thirst, and their travail, and so forth.

38 And he also rehearsed unto them concerning the rebellions of Laman and Lemuel, and the sons of Ishmael, yea, all their rebellions did he relate unto them; and he expounded unto them all the records and scriptures from the time that Lehi left Jerusalem down to the present time.

So... he read to them from the Book of Mormon, just not yet bound or abridged.

Truly this book changes lives.

It has mine.
