12 And it came to pass that there were many of the ^apeople of Ammon, who were Lamanites by birth, did also go forth into this land.

  6 And it came to pass that many of the Lamanites did go into the land northward; and also ^aNephi and ^bLehi went into the ^cland northward, to preach unto the people. And thus ended the sixty and third year.
