Enoch - Observe and see how (in the winter) all the trees ⌈⌈seem as though they had withered and shed all their leaves, except fourteen trees, which do not lose their foliage but retain the old foliage from two to three years till the new comes.
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.
