3 Nephi 16:1-3

1 And verily, verily, I say unto you that I have other sheep, which are not of this land, neither of the land of Jerusalem, neither in any parts of that land round about whither I have been to minister.

2 For they of whom I speak are they who have not as yet heard my voice; neither have I at any time manifested myself unto them.

3 But I have received a commandment of the Father that I shall go unto them, and that they shall hear my voice, and shall be numbered among my sheep, that there may be one fold and one shepherd; therefore I go to show myself unto them.
