So, on one of the Discovery or NatGeo programs they actually investigated this.
There are Jewish peoples in Ethiopia going back to just after Moses, I think? Not sure on time period.
But, the story is that a fake was kept in Jerusalem at a time when threats of invasion worried the Israelites enough to have the original moved to their Jewish brethren in Ethiopia to keep it safe.
It's just another "hypothesis" like many others, but there are reasons to give it some credence.
Most can simply Google it:
According to Jewish traveler,
Eldad ha-Dani, the
Tribe of Dan established their own kingdom in Ethiopia, "They went by way of Egypt further down the upper Nile River and settled in Ethiopia, in East Africa. The Danites were great warriors, and after fighting many battles against native tribes, they established themselves securely, with a kingdom of their own."
Marco Polo and
Benjamin of Tudela also mention the existence of an Ethiopian Jewish community.[url=https://en.wikipedia.org/wiki/History_of_the_Jews_in_Ethiopia#cite_note-FOOTNOTEFauvelle-Aymar2013383-3][3][/url]
Christian dominance (12701855)The earliest recorded mention of the Beta Israel comes from the
Royal Chronicle of Emperor
Amda Seyon, who sent troops to pacify the northwest provinces of
Semien,
Tselemt,
Tsegede and
Wegara where the Beta Israel had been gaining prominence.[url=https://en.wikipedia.org/wiki/History_of_the_Jews_in_Ethiopia#cite_note-PankBord40-4][4][/url] He sent troops there to fight people "like Jews" (

kama ayhd).[url=https://en.wikipedia.org/wiki/History_of_the_Jews_in_Ethiopia#cite_note-Encyc553-5][5][/url]
According to both Ethiopian written accounts and Beta Israel oral tradition,
Emperor Yeshaq (14141429) began to exert religious pressure on the Beta Israel which sparked a revolt.[url=https://en.wikipedia.org/wiki/History_of_the_Jews_in_Ethiopia#cite_note-FOOTNOTEKaplan2007501-6][6][/url] Following the defeat of the rebellion, Yeshaq divided the territories of the Jews into three provinces, which were controlled by commissioners appointed by him. He reduced the Jews' social status below that of Christians[url=https://en.wikipedia.org/wiki/History_of_the_Jews_in_Ethiopia#cite_note-Encyc553-5][5][/url] and forced the Jews to convert or lose their land. It would be given away as
rist, a type of land qualification that rendered it forever inheritable by the recipient and not transferable by the Emperor. Yeshaq decreed, "He who is baptized in the Christian religion may inherit the land of his father, otherwise let him be a
Fals." This may have been the origin for the term "Falasha" (
fal, "wanderer", or "landless person").[url=https://en.wikipedia.org/wiki/History_of_the_Jews_in_Ethiopia#cite_note-Encyc553-5][5][/url] This term is considered derogatory to Ethiopian Jews.
