Another verse to consider:

And he took up his parable and said--Enoch a righteous man, whose eyes were opened by God, saw the vision of the Holy One in the heavens, which the angels showed me, and from them I heard everything, and from them I understood as I saw, but not for this generation, but for a remote one which is for to come.

• 1 Enoch 1:2



• Maybe this is why The Book of Enoch was lost for so long.
