This could be approached by tracing the story of the dispersion of the Jews and/or by the study of tribal beliefs and practices and the records of early African travellers before the inroad of Islamism/Christianity desstroyed all the traditions of the past.

The Ashantis of West Africa

Of all the Tshi-speaking races, the Ashantis have the most marked characteristics. Their skill and bravery in war, their diplomacy, and their singular patriotism and power of combination and organization, not only made them the most formidable people in the Gold Coast, and the founder of only the most important kingdom there, but also enabled them to become masters of the whole country and coast. ~ Lord Wolseley 1874

"From Ethiopia, Middle Egypt and Central Sudan, descended the Ashanti and the tribe known as Bantu."

"Most of the higher classes of Ashanti are descended from eastern Ethiopia. The prefix Sai or Zai to the names of the Ashanti kings a remnant of the Abyssinian Za or Zo, prefix of the shepherd kings or original Ethiopians which was sometimes pronounced as Zai or Sai.
The succession of Ashanti kings is thru the sister of the late king to his nephew. The Abyssinians, like the ancient Egyptians, never fight in the night, neither do the Ashantis. The Ashantis never fight on a Saturday. This last rather savors Judaism."

Stripping to the waist as a sign of respect is found among the Abyssinians and Ashantis alike. Both nation begin their year at about the same time in Autumn. The civil new year of the Jews (Rosh Ha-Shanah) also occurs in September or early October.

The term obeah, obiah, or obia is derived fron Obayifo, a witch. The etymology of the word Obi is traced to the Egyptian Ob, a serpent, whose practice is a form of Egyptian Ophiolatry. The origin of the terms Obeah and Obi can be traced to the Canaanite superstition of the Ob or Oub...as in the witch of Endor whom Saul (old testament bible) consulted. ASA OB was one of the crimes charged against King Manasses. Ashantis can ultimately trace their connection to the tribe of Manasses.

The very name "Ashanti" has a strong Hebraic flavor. Ashanti means the people of Ashan. In the domain of Judah, there was a town named Ashan. Priests were in residence there according to the First Book of Chronicles where the word is spelt ASHAN. Though in the correspinding passage of Joshua it is spelt AIN, which the Jewish encyclopedia described as a corruption of Ashan.

Endogamy:

Ashanti has a number of customs and practices that find their counterparts among the ancient Hebrews. For example, the Mosaic Law of intra-tribal marriages, which was devised expressly to preserve the inheritance of the daughters "in the tribe and family of their father" (See Numbers Chapt 36 vs 5 - 12). The Ashanti (even of today) practice cross-cousin marriages, characteristic of the Hebrews which are strictly similar to that of the daughters of Salphaad who wedded "the sons of their uncle by their father." See Numbers Chapt 36 vs 11.

They also preserve certain names in the family as it was of old among the Hebrews as was the case during the naming of John the Baptist, when objection was made: "There is none of thy kindred that is called by this name." (Luke Chapt1 Vs 61)

Marriage Rite:

Before a proposal of marriage, and the consequent seeking of the consent of the parents...and the exchange of gifts, it is the business of the young people to satisfy themselves that the union would not violate any of the forbidden degrees of consanguinity. The ancient Hebrews themselves coud not have been more particular in this regard. They have obained the parents' consents, the Ashantis youth will make them smallgifts and pay the bride price including the wine offering. The parents consent, the presentation and acceptance of these gift, and the aseda (bride-price) are the only formalities that are necessary to constitute a valid amrriage. The wine is used in the religious part of the marriage rites...and also handed round to those who are present.
In ancient Hebrew marriage, the ceremony was performed in a private house, without the necessary presence of priest or rabbi. An elder invoke the bendiction and gave a cup of wine to the contracting parties who pledged to each other. After marriage customs are similar to the Ashanti.

Uncleanliness after birth, Purification, Menstrual seclusion:

For eight days after the birth of a child, the Ashanti "mother is considered as unclean."
It is only on the eight day, at the Ntetea rite, as the Ashanti call it, that the child receives its personal name. On the forthieth day, a further ceremony has to be observed. Same are the Hebrew customs.

Further, the restrictions and taboos of the Ashanti woman at the menstrual period, even to the retirement of the bara hut, read like a page from the book of Leviticus, and the system of Ashanti ablutions to prevent legal unclaenliness constantly reminds of similar practices common among the Hebrews.

Supreme Being of the Ashanti:

"I am convinced that the conception in Ashanti mind, of a Supreme Being, has nothing whatever to do with missionary influence, nor is it ascribed to contacts with Christians or Mohammedans. This Supreme Being, the conception of whom has been innate in the minds of the Ashanti, is the Jehovah of the Israelites."

Supreme Being - Onyame
In normal conversation, the prefix O is generally elided. The prefix N placed in front of the verb to form nouns lleaves as the significat part of the word Yame. In Ashanti, the letter M interchanges with W to represent the same sound. This establishes the similarity between Ashanti Yame and the Hebrew Yahweh.

Hebrew: HAYAH - to be (verb)
Ashanti: Yeh - to be
Hebrew: Bara - to create
Ashanti - Bore - Creator

The Ashanti tribal worship is strangely parallel to that of divided worship that existed in Jerusalem immediately prior to the Babylonian exile.

Alter of Nyame:

Among the stamps patterns of the ashanti cloths recently reproduced by Rattray, there is one striking design known as "Nyame dua" or Alter of Nyame." In the case of Mosaic Alter of Sacrifice, the horns at the corners are turned in instead of outward.
