Halakhah for Temurah 58:24

From the laws of the commandment is that which they, may their memory be blessed, said (Niddah 32a) that a woman becomes impure as a menstruant even on the day of her birth; whereas the law is not like this with a zavah - as a woman does not become impure with a discharge until ten days [of age]. And this thing is by way of the heard tradition. And all women are included in this prohibition, and even Canaanite (gentile) maidservants - since they are included in the commandments, they are like Israelitesses for this matter (Sifra, Metzora Parashat Zavim, Section 5:1). But the women of the [other] nations of the world are not included in the prohibition of menstruation and discharge from Torah writ, but rather [only] rabbinically. As they decreed about them - whether males or whether females - that they be like a zav for all their matters (Niddah 34a). And that which they said in the Gemara (Avodah Zarah 36b) that one who has intercourse with a gentile woman is liable because of her on account of nashgaz (the acrostic of the four prohibitions about to be named) - the explanation of which is a menstruant, a maidservant, a gentile woman and an unfaithful woman (zonah). And this liability is only rabbinic for an Israelite. But for a man who is a priest, he is liable because of her from Torah writ on account of an unfaithful woman (Temurah 29b); and he is lashed because of her.
