In post modern scholarship, there is skepticism as to whether there ever were twelve Israelite tribes, with the use of the number 12 thought more likely to signify a symbolic tradition as part of a national founding myth,[1] although most scholars disagree with this opinion.
[2] Jacob, later called Israel, was the second-born son of Isaac and Rebecca, the younger twin brother of Esau, and the grandson of Abraham and Sarah.
The sons of Jacob were born in Padan-aram from different mothers, as follows:[4] Deuteronomy 27:12–13 lists the twelve tribes: Jacob elevated the descendants of Ephraim and Manasseh (the two sons of Joseph and his Egyptian wife Asenath)[5] to the status of full tribes in their own right due to Joseph receiving a double portion after Reuben lost his birth right because of his transgression with Bilhah.
[6] In the biblical narrative the period from the conquest of Canaan under the leadership of Joshua until the formation of the United Kingdom of Israel passed with the tribes forming a loose confederation, described in the Book of Judges.
Modern scholarship has called into question the beginning, middle, and end of this picture[7][8] and the account of the conquest under Joshua has largely been abandoned.
According to the Babylonian Talmud (Baba Bathra 106b), the lots did not actually function as a legal allocation of property but only clarified the division.
[35] Translator Paul Davidson argued:[36] "The stories of Jacob and his children, then, are not accounts of historical Bronze Age people.
"[33] Historian Immanuel Lewy[37][38] in Commentary mentions "the Biblical habit of representing clans as persons.
Sidon, a Phoenician town, is the first-born of Canaan; the lands of Egypt and Abyssinia are the sons of Ham.
"[39] Norman Gottwald argued that the division into twelve tribes originated as an administrative scheme under King David.
[42][43] Recent studies of genetic markers within Jewish populations strongly suggest that modern Ashkenazi Levites (Jewish males who claim patrilineal descent from the Tribe of Levi) are descendants of a single Levite ancestor who came to Europe from the Middle East roughly 1,750 years ago.
This means that a relatively small number of original ancestors have had a large impact on the genetic makeup of today's Ashkenazi population.
