2 Nephi 27:10

but the words which are sealed, he shall not deliver, neither shall he deliver the book. For the book shall be sealed by the power of God, and the revelation which was sealed, shall be kept in the book until the own due time of the Lord, that they may come forth: for, behold, they reveal all things from the foundation of the world, unto the end thereof.

But the sealed words he will not share. He will not give away the book. For the book will be sealed by God’s power. The sealed message will be kept in the book until the Lord’s own time. Then they may come out. For they tell about all things from the beginning of the world to the end.

But the sealed words he won’t deliver, and he won’t hand over the physical book. The book will be sealed by God’s power, and the sealed revelation will stay in the book until the Lord’s appointed time, when they can finally come out. These sealed things reveal everything from the creation of the world to its very end.
