Interestingly enough, the Enoch Scroll was part of the Dead Sea Scrolls found at Qumran.
And, IIRC, the prophecy of Enoch, like certain parts of Daniel’s prophecy, was said to be “bound up” until the last days.
You said — “... until the last days.”
Are we there yet.... :-)
And, Enoch’s book was mentioned in the Bible a number of times as valid and authoritative while not considered Canon.
