If by "near eastern" you mean Khazar, then yes.

This is the paper you linked to btw, just absolute mythical nonsense:

> Cohanim (plural of “Cohen,” the Hebrew word for priest) are, in Biblical tradition, the descendants of Aaron the brother of Moses; Levites are, in that tradition, considered to be those male descendants of Levi, the third son of the patriarch Jacob and paternal ancestor of Aaron, who are not Cohanim. The Cohanim have both rights and duties in religious law, as well as being subject to restrictions that do not apply to the other castes.
