Helaman 15:13

and this is according to the prophecy, that they shall again be brought to the true knowledge, which is the knowledge of their Redeemer, and their great and their true Shepherd, and be numbered among his sheep.

This follows the prophecy. They will learn the true knowledge again. They will know their Savior. They will know their great and true Shepherd. They will be counted among his sheep.

The prophecy says they’ll be brought back to true knowledge—knowledge of their Redeemer, their true Shepherd—and they’ll be counted among his flock.
