Clayton Brough notes that as the Lost Ten Tribes made their way northward through the unknown region of “Arsareth,” they were “led by prophets and inspired leaders” who “were guided by the spirit of revelation, kept the law of Moses, and carried with them the statutes and judgments which the Lord had given them in ages past.” Indeed, the spirit of the Lord continually watched over the Lost Ten Tribes of Israel and guided them throughout their journey northward. (See Jeremiah 23:7-8; 16:14-15)
In regard to other spiritual events that later transpired among the Lost Ten Tribes, such as the Lord personally visiting them following his ministry to the Nephites on the American continent, their being taught the Gospel, and their creating and maintaining volumes of scripture, Elder Bruce R. McConkie has written:
In their northward journeyings they were led by prophets and inspired leaders. They had their Moses and their Lehi, were guided by the spirit of revelation, kept the law of Moses, and carried with them the statutes and judgments which the Lord had given them in ages past. They were still a distinct people many hundreds of years later, for the resurrected Lord visited and ministered among them following his ministry on this continent among the Nephites. (see 3 Nephi 16:1-4; 17:4) Obviously he taught them in the same way and gave them the same truths which he gave his followers in Jerusalem and on the American continent; and obviously they recorded his teachings, thus creating volumes of scripture comparable to the Bible and Book of Mormon. (See 2 Nephi 29:12-14) (Bruce R. McConkie, Gospel Doctrine, pp. 457-458
Brough notes that following our Lord’s resurrection and personal visit to the peoples of the Lost Ten Tribes of Israel, our Savior also assigned one of his chosen Apostles, John the Revelator, who is presently a “translated being,” to watch over the Lost Ten Tribes and to assist them in preparing for their future return from “the land of the north.” (R.
