I would love to have some discussion on the Book of Enoch.
Biblically, the idea of hell changed drastically from the Old Testament to the New Testament. While there were some vague ideas of a punishment of the angels (Isaiah 24:21), and a mention of a resurrection of the dead to ever lasting life or everlasting disgrace (Daniel 12:2), most concepts of Hell -- The Lake of Fire, The Pit, Outer Darkness -- weren't described in detail until Jesus's time and after.
This is where the Book of Enoch is strange to me. It talks about many of these "new" concepts in depth and is dated at least 100 years before Jesus. Many of the teachings of Hell and punishment of the angels in the New Testament (Jude 1:6, 2 Peter 2:4, Revelation 9:1–2; 19:20, 20:1–3, 20:10, 20:14–15) are paralleled in Enoch.
How do you all think about this stuff?
