John Nash commands and does

A. I understand that you mean to say that he had objective indications that he was wrong? I don't know what Nash had in reality. B. I didn't understand the question. Do you mean that because there is no obligation until the age of 12, then all the mitzvot are in the context of the time of the german? This is clearly not true, because it is a fact that women are indeed obligated in the mitzvot that are not in the time of the german. But this is not just a special geziyyah. A mitzvah that begins at a certain age and continues from there (like circumcision, for example) according to how many Rishonim is not considered to be in the time of the german. And in general, all the mitzvot began at Mount Sinai, so they are caused by historical time.
