After learning about normative Judaism in the 19th century, the Bene Israel often migrated from villages in Konkan[28] to nearby cities, which included Mumbai,[29] Pune, Ahmedabad, and Karachi, in today's Pakistan.[30] Based on Bene Israel tradition, after centuries of traveling through western Asia from Israel, their ancestors migrated to India and slowly assimilated to their surrounding community, while maintaining particular Jewish traditions.[31] David Rahabi, an Indian Jew, found the Bene Israel in the 18th century and took note of their Jewish customs.[32] Some historians note that the ancestors of the Bene Israel belonged to the one of the Lost Tribes of Israel;[33] however, Jewish authorities have not officially recognized the Bene Israel as one of the Lost Tribes.[34] According to the Jerusalem Post, in 2002, a DNA study linked the descendants of Bene Israel to the Cohanim (Tribe of Levi).[35]
