Seif 4 - A mamzer is like a (regular) Jew and we bless the blessing for circumcision until [the point in the blessing when it says] “who makes the covenant”, and we do no has for mercy for him. And we make it public knowledge during his circumcision that he is a mamzer). During Yom Kippur and the other 4 fasts one should not make the blessing over a cup [of wine], however, during the three fasts where a woman who has recently given birth does not need to fast, it is permissible to make the blessing over a cup [of wine], and the woman should taste it if she hears the blessing and intends not to make an interruption between hearing the blessing and drinking the wine, but during Yom Kippur and the 9th of Av, when the woman who has recently given birth is not allowed to drink, we do not make the blessing over a cup [of wine], and during the 9th of Av we do not bring a myrtle, because the reasoning being that we (similarly) don’t make the blessing over the spices when the 9th of Av falls on Saturday night. Rema: And there are those who say that one makes the blessing over the cup [of wine] on all of the fasts, and he gives the blessing (i.e. the wine on which the blessing was made) to the small children. And this is how we practice, and during Yom Kippur, our practice is to give [some wine] to the child who was circumcised. And there are those who say that this is sufficient even when it is not a fast day, but we don’t practice accordingly; rather, the sandek should drink [from the cup] when it is not a fast day.
