One of the most frequently asked doctrinal questions since the early days of the Church concerns the history and whereabouts of the Israelites sometimes called the "lost ten tribes." Yet "Where are the lost ten tribes?" is not a Latter-day Saint question at all. It was brought into the Church by early converts from other denominations, who were already speculating concerning it. It was asked more commonly in past generations, but even today the question still arises. It is unfortunate that it should be asked at all, however, because latter-day revelation gives clear teaching on the subject—as does the Bible. The expression "lost tribes" is found in only two verses of scripture—both in the Book of Mormon (see 2 Ne. 29:13; 3 Ne. 17:4). Both passages refer to members of the house of Israel outside their ancestral homeland. Nephi indicates that the word lost shows the perspective of the Israelites in Palestine: the "lost" tribes were simply "lost from the knowledge of those who are at Jerusalem" (1 Ne. 22:4). Thus those people are Israelites who were removed from Palestine and whose history was unknown to those who remained, including to the writers of the Bible and the Book of Mormon.
