Mosiah 1

My sons, I would that ye should remember that were it not for these plates which contain these records and these commandments, we must have suffered in ignorance, even at this present time, not knowing the mysteries of God. For it were not possible that our father Lehi could have remembered all these things, to have taught them to his children, except it were for the help of these plates. For he having been taught in the language of the Egyptians, therefore he could read these engravings and teach them to his children, that thereby they could teach them to their children, and so fulfilling the commandments of God even down to this present time. I say unto you my sons, were it not for these things which have been kept and preserved by the hand of God, that we might read and understand of his mysteries and have his commandments always before our eyes, that even our fathers would have dwindled in unbelief.
