Reply To: Full Sibling or Half-Sibling

I have just this week talked about this with someone. Obviosuly it is true as the shvatim were considered full brothers, but it never quite made sense to me, as the MOTHER is the one in whose body the children develop, and the religion goes according to the mother,and when we make a mi sheberach for a choleh we use the mother’s name (because it is always a possibility however remote, that the father was not the actual father). I guess the answer is that the Halacha is the Halacha, and Hashem knows the answer, even if some of us don’t quite “get” it.
