   34 And it came to pass on the morrow, that the firstborn said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father.
2. 1 Ne. 3: 19-20
   19 And behold, it is wisdom in God that we should obtain these records, that we may preserve unto our children the language of our fathers;
   20 And also that we may preserve unto them the words which have been spoken by the mouth of all the holy prophets, which have been delivered unto them by the Spirit and power of God, since the world began, even down unto this present time.
