This Book of Enoch offers additional context to the many references to Enoch in the Bible. When I took the time to read this book, it brought a lot of clarity around the person of Enoch, who is from the line of Seth, and is the grandfather of Noah.
The Bible mentions Enoch as a man who walked with God. Additionally, while everyone else in the line of Seth in Genesis died, the Bible says that Enoch walked with God and then God took him – as in, he didn’t die.
Enoch was 65 years old when he fathered Methuselah. And after he fathered Methuselah, Enoch walked with God 300 years and fathered other sons and daughters. So Enoch’s life lasted 365 years. Enoch walked with God; then he was not there because God took him.
While this book is not a part of the official Biblical canon, I personally believe that it offers vital context, that allows for a deeper understanding of the Bible and therefore highly recommend it.
