Yossi Cohen? You notice that he changed his first name but not his last name like the rest of the Jews in Palestine have done and the reason is because his last name is supposed to be a high class of a Jew. This is what it says on the internet about the name Cohen:
Cohen, Jewish priest, one who is a descendant of Zadok, founder of the priesthood of Jerusalem when the First Temple was built by Solomon (10th century bc) and through Zadok related to Aaron, the first Jewish priest, who was appointed to that office by his younger brother, Moses.
I have seen so many DNA results of Jews by the name of Cohen and they too are just 100% Ashkenazi. These people need to remove the delusion in their heads that they are related to this or that character from the Bible.
