That book is full of nonsenses and idiocy absurdities. I translated whole Book of Enoch, and believe me, there is nothing vlauable in it.
You know Aramaic? I get the feeling you're referring to the fake Slavic Book Of Enoch and not the one from the dead sea scrolls.
P.S. Jude really doesn't quote from The Book of Enoch
Enoch 1:9 And behold! He cometh with ten thousands of His holy ones. To execute judgment upon all, and to destroy all the ungodly; And to convict all flesh of all the works of their ungodliness which they have ungodly committed, and of all the hard things which ungodly sinners have spoken against Him.
Jude 1:14 And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints, 15To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him.
Unless Jude spoke to Enoch face to face, he has to be quoting from the Book Of Enoch.
