Abraham's sons of Keturah (Ḫattuša) were endowed with spiritual gifts and sent to the east. They are associated with Y-DNA Haplogroup http://en.wikipedia.org/wiki/Haplogroup_R_(Y-DNA).
Traditions concerning the Keturahites in both Genesis 25, the book of Jubilees, and among Talmudic Jews mention them being sent to Kedem with "Spiritual Gifts". They were required to keep the milah among their comission and observe certain moral and ethical standards -the ways of the Hanif having power over serpents.
