3 Nephi 28:36

And now behold, as I spake concerning them whom the Lord had chosen, yea, even three which were caught up into the Heavens, that I knew not whether they were cleansed from mortality to immortality:—

I talked about the three people the Lord chose. They were taken up into heaven. I said I did not know if they had changed from bodies that could die to bodies that would live forever.

Now, about those three the Lord chose—the ones caught up into heaven—I said earlier that I didn’t know if they were changed from mortal to immortal.
