Around 733 B.C., ten of the twelve tribes of Israel were conquered and exiled by the Assyrian Empire. Where did the Gadarenes of Gadara go when they were exiled? Can we trace them through to the 21st Century in Europe? The ancient tribe of Gad was exiled from Israel in ancient times and prophesied to return. They have been considered lost forever. New evidence suggests that the tribe is actually alive and well. (Simcha Jacobovici, 2015)
