1 Nephi 12:11

And the angel said unto me: Look!

And I looked, and beheld three generations pass away in righteousness;

and their garments were white even like unto the Lamb of God.

And the angel said unto me:

These are made white in the blood of the Lamb,

because of their faith in him.

and their garments were white even like unto the Lamb of God.
