Reply To: This Has Nothing to do With Techeiles PBA

After thinking about it, I actually do like your answer, but I would just phrase it slightly differently: The issue of dayo is that the halacha that you are applying to the second case has to be the same as the halacha in the first case. As opposed to here where the halacha is the same but the situation of the first case is not the same as the first case. (I think that is what you were saying.) My issue though, is that if this is a good chiluk then the Medrash Shmuel should never have had his question in the first place because presumably it’s a din in when the rules of dayo apply, not a specific chiddush in being mafrich the k”v.
