Kohen or cohen (plural kohanim) is the Hebrew word for priest. According to Judaism Kohanim are supposed to be of direct patrilineal descent from the biblical Aaron. Therefore, Jewish propaganda markets the notion that this particular Jewish lineage as a pure pedigree. Quite apart from the fact that the Bible as a historical and scientific source leaves much to be desired the Semite itself is not a pure racial type but a composite. Nevertheless, those of this line are given special status among the Jewish tribe and in the terrorist state of Israel there are specific laws governing their marriage.
