In Rabbi Avichails book "Tribes of Israel", there is translated and
transcribed Rav Kook's approbation to R' S. Horowitz's Sefer on the
Jews around the world in the early 1900's.

In it Rav Avraham Yitzchok HaKohein Kook discusses 3 groups of Israel
which were exiled. The Ten Tribes, The Sons of Moses and The Sons of
Rechav. Respectively, Rav Kook says these groups represent the
Strength, the Secret Treasures of the Torah, and the Purity of Living
of Israel and when these 3 groups return with them comes these 3 traits.

The Bnei Moshe are identified with the Musazai and Musakhel.
