2 Nephi 27:7

And behold, the book shall be sealed; and in the book shall be a revelation from God, from the beginning of the world, to the ending thereof.

The book will be sealed. In the book will be a message from God. It will go from the beginning of the world to the end of it.

The book will be sealed, and it will contain revelation from God stretching from the beginning of the world to its end.
