The Book of Jasher and the Holy Bible - A Parallel Reading. While reading through The Book of Jasher I found myself often flipping through the Pentateuch for cross referencing. Hence the idea for this book. You will find an amazing amount of almost word-for-word parallels which lead one to wonder if perhaps one was a source for the other, or at the very least Moses and the author(s) of this book drew from the same oral traditions. To me this speaks well of the historical accuracy of this text and that it isn't some authors imaginative "filling in" details in the Biblical record.
