- Question: Why can a half slave half free man get married misafek (at least in doubt, see Avnei Miluim 44:3) but he definitely can’t blow shofar for himself or anyone on Rosh HaShana (See Gemara Rosh HaShana 29a)
A. The Avnei Miluim gives a difference between a half maid servant half free woman and a half slave half free man in that she can definitely accept marriage because she’s doing nothing, just nullifying her will and knowledge to her would be husband and he is doing the act of marriage. Whereas a half slave half free man since he is doing the action and his half slave side isn’t able to perform a Halachic marriage for his free man side therefore it is questionable whether he can get married.
B. By blowing a shofar since the half slave side isn’t obligated in blowing shofar it can’t help it’s free side blow shofar but if he heard someone else blow shofar then his free side can accept the blow he heard and fulfill the mitzvah.
C. A half slave half free man is one body with two sides or parts to him (or more like two men.)
Answer: Blowing the shofar is dependent on the body since the body is blowing. So since he is one body then both sides are blowing. But marriage doesn’t happen through the body but by the person with his knowledge to get married so now that we are saying they are like two guys inside one body and granted they are both doing the marriage but the slave side doesn’t take away from the free man’s side so the free man’s side might possibly work to create a marriage.
