I'm familiar with non-canonic books that are mentioned in the Bible such as the Book of Enoch, which I've read, but I was just reading from Numbers in the Old Testament, and it mentions a Book called the "Book of the Wars of the Lord"...I now need to read this book. That sounds really badass. Any have resources regarding this?

EDIT: Just realized the mistake in my title, should be "The Book of the Wars of the Lord".
