A daughter of a male disqualified priest (halal) is disqualified from [marrying into] the priesthood forever. Rabbi (sic!, based on Ehrfurt manuscript) says: A daughter of a male convert is like the daughter of a male halal and disqualified from the priesthood. An isah is disqualified from the priesthood (see previous halakhah); if she [the isah] got married to a Yisrael, her daughter is fit [to marry into] the priesthood. A captive woman is disqualified from the priesthood; if she got married to a Yisrael, her daughter is fit for the priesthood. A freed handmaid is disqualified from the priesthood; if she is married to a Yisrael, her daughter is fit for the priesthood. It turns out that Yisrael is a mikveh for priests [since the daughter of a pesulah with a male Yisrael is no longer pesulah] and a handmaid is a mikveh for all disqualifications.
