민수기 1:18 할라카: Sefer HaChinukh

A priest that has intercourse with a possibly licentious woman, such as a possible convert or freed [maidservant], or with a possible divorcee; and so [too,] a high priest who has intercourse with a possible widow — behold this is a doubtfully profaned woman and the offspring is a doubtfully profaned priest. It comes out that there are three [types of] profaned priests: a profaned priest from Torah writ; a profaned priest from the words of [the Rabbis]; and a doubtfully profaned priest. And we give upon any doubtfully profaned priest or profaned priest from the words of [the Rabbis] the stringencies of the priests and the stringencies of the Israelites. He does not eat from the priestly tithe and does not become impure for the dead and he must marry a woman that is fitting for a priest. And if he ate priestly tithe or became impure or married a divorcee, a profaned woman [or a] licentious woman, we strike him with rabbinic lashes of rebellion. But behold, a certainly profaned priest from Torah writ is like a non-priest and marries a divorcee and becomes impure for the dead; as it is stated (Leviticus 21:1), “Speak to the priests, the sons of Aharon” — even though they are sons of Aharon, [not] until they are in the [their] priesthood. And they, may their memory be blessed, also received (Sifra, Emor, Section 1:2) as the explanation of that verse, “‘The sons of Aharon,’ and not the daughters of Aharon — from here that fit women are not warned (prohibited) from marrying disqualified ones.” And so a priestess is permitted to marry a profaned priest, a convert and a freed [slave]. And therefore they, may their memory be blessed, said (Kiddushin 73a) that a convert is permitted to marry a priestess and a mamzeret: a priestess for the reason we said, that they were not warned from marrying ones disqualified; and a mamzeret on account that the congregation of converts is not called a congregation — and with the prohibition of the mamzer, it is written (Deuteronomy 23:3), “A mamzer shall not come into the congregation of the Lord.” And that which they said (Kiddushin 77a) that all the seed of a profaned priest that married a fit woman are profaned priests and disqualified to the priesthood; since the offspring goes after the father in this matter, as it is stated (Numbers 1:18), “and they shall be pedigreed by their families [according to the houses of their fathers].” And any widow from a family into which a possible profaned priest was mixed is forbidden to a priest at the outset. But if she married [him], she should not leave (be divorced) — since there is a double doubt. And we are not concerned about a double doubt, even in a [law] of Torah writ. But if a certainly profaned priest is mixed into a family, every woman from it is forbidden to marry a priest, until he examines [her lineage]. And the rest of its details are in Kiddushin and Yevamot.
