Enoch - And the sheep went to the wolves according to the word of the Lord, and another sheep met it and went with it, and the two went and entered together into the assembly of those wolves, and spake with them and admonished them not to touch the sheep from henceforth.

Notes

The book of Enoch is not part of the canonical scriptures (The Bible) we know today and we don't know how accurate it is.

Some belive while Enoch is not inspired by God that it still serves as a historical book on the time before the flood. It's also quoted in the New Testament in Jude 1:14-15.

Because of this I wanted to include this book for historical reasons.

I would recommend reading the Bible first and foremost as it should be your foundation. Then if you are intrested you can take a look at the book of Enoch.
