We have discussed the “ten lost tribes” of Israel several times in our study of Hosea. Yet many Christians do not believe there are descendants of Ephraim out in the world awaiting discovery and restoration to their ancestral homeland.
Partly this is an overreaction to British Israelism, a 19th century movement that claimed the people of Great Britain (and therefore most of the New World) were genetically, racially and linguistically the direct descendants of the ten lost tribes of Israel. Despite its comprehensive refutation by archaeological, ethnological, genetic and linguistic research, BI still has its adherents, and therefore a significant number of Christians who feel compelled to keep reacting to and refuting their claims.
