In Moses 1:41 we read:
And in a day when the children of men shall esteem my words as naught and take many of them from the book which thou shalt write, behold, I will raise up another like unto thee; and they shall be had again among the children of men—among as many as shall believe.
This echoes 2 Enoch 35:1-3 which reads:
And I will leave a righteous man (Noah), a member of your tribe, together with all his house, who will act in accordance with my will. And from their seed will arise a generation, the last of many, and very rapacious. And I shall raise up for that generation someone who will reveal to them the books in your handwriting and those of your fathers, by means of which the guardians of the earth will show themselves to the faithful men. And they will be recounted to that generation, and they will be glorified in the end more than at the first.
Where was Joseph Smith getting all this information on Enoch?
