Edited sentence: An Egyptian writer--Ahmed Osman--has claimed that Ephraim may be identified with Pharaoh Ay, who is thought by some scholars to be a son of Yuya, a powerful court official under Amenhotep III.However, Ay's parentage--which has been the source of much speculation among Egyptologists--remains unknown from contemporary Egyptian records and Osman's claim is not followed by mainstream Egyptologists.Osman, in turn, thinks he may be identified as Joseph, the Pharaoh's Viceroy in the Bible.The only thing that is certain is that Yuya was the father of Queen Tiye, Amenhotep III's chief wife, and Anen, her older brother.Yet, very interestingly enough, Ephraim is said by Hebrew tradition to eventually rule Egypt as Pharaoh, but, although Egypt previously temporarily was made to worship the God of the Israelites, Ephraim later allowed them to worship their previous gods and idols, which is exactly the case with Ay (if there is a connection between Aton and Adonai)
