Og`s offspring – are they "Bnei Noach"?

shmoel – Even if his children would have married Bnei Noach, it is only with Jews that yichus (as to nationhood) is matrilineal. For everybody else it is patrilineal, hence Og’s sons would be Bnei Og, and if they would have married daughters of Bnei Noach their children would also be Bnei Og. Only the daughters’ children would become Bnei Noach by virtue of being the children of male Bnei Noach. Whilst, over time, this would mean that the vast majority would become Bnei Noach, there would always be a few who were ben achar ben from Og and therefore not Bnei Noach. So to say “all would be Bnei Noach” is incorrect. The vast majority, maybe, but not all.

I do, however, agree that it is far from certain that Og had any children post-mabul. At any rate, bizman Avraham Avinu, Og was not married.

Just my hapence, only religious identity is matrilinial. Nationhood was patrilinial. If your parents came from different shvatim, you belonged to your father’s. Your identity as kohen, levi or yisroel is determined by your father, not mother

Perhaps professional basketball players are Bnai Og.

would a bnei og have to keep the 7 mitzvot of bnei noach?

Yes, because the term “ben Noach” in this case is merely a shorthand for “humanity.”

Noach’s ancestors also had to keep the seven (six) mitzvos — and they certainly weren’t “b’nei noach.”

well maybe noach made it that since he saved the animals humans in general are above them therefore we can eat them

According to one answer in the Ramban it comes out that Noach’s daughter’s-in-law were children of the giants. This is another explanation how the giant race survived the Mabul.

According to the other answer that Og himself survived, the Navi in Yehoshua explains that all the giants in Eretz Yisrael were defeated by Yehoshua and his army. The only four remaining giants lived in the land of the Plishtim. They were Goliass and his three brothers. Dovid and his army killed them in later years. This is why there are no giants today. I can look again for the sources for all this if anyone is interested.

Anyways, some of the 7 Mitzvos were given to Adam and therefore would apply to Og too.

Moshe was an exception in many ways. He was prepared already from birth to be the leader. This may have included the correct physical build required for the proper respect he deserved

shmendrick – So you can quote Pirkei D’Rebbi Eliezer and Yalkut Shimoni, and yet you seem not to know basic Chumash. The ben achar ben lineage of Kayin died out in the 7th dor with Yuval, Tuval and Tuval Kayin. And their sister, Na’amah, was Noach’s wife, which would make us all of ‘cursed lineage’ if ben achar ben is not important. Besides, the shitta that Og lived before the mabul and survived is based on his identification as ‘hapolit’ from the milchama of the 4 kings vs the 5 kings, the same medrash saying that his intentions were that Avraham would die and he could marry Sarah (hence the inference that he was not married at the time, Wolf…), and thus being descended from the ‘Nefilim’, who were from neither Shes nor Kayin (see Rashi there). The identity of these Nefilim is somewhat controversial, but see Ramban there. In any case, Og was most definitely NOT descended from Kayin, at least not ben achar ben.

shmendrick – As I thought I made clear, ben achar ben lineage from Kayin is impossible as they all died, even before the mabul. If not ben achar ben, then we are all ‘cursed’ as Noach’s wife was from Kayin. Besides, as I then made clear, Og was descended from the Nefilim who were definitely not from Kayin either. So no, Og may NOT have been from Kayin. And I have already answered the original question.
