The Midrash relates that Og, later to become King of Bashan, survived the flood in the generation of Noach (Pirkei d'Rabbi Eliezer, 23). Was he responsible for following the seven commandments despite not being a member of Noach's family?
Edit:
As DoubleAA wrote in the comments below, I am asking whether the change to Noachide law applied to Og, or whether he was bound by the previous code.
