Talmud su Levitico 21:2

For his betrothed wife one does not mourn, grieve,⁹‘Or grieve’ is added by GRA and H. or [if a kohen] defile himself.¹⁰The duty of mourning, etc., for a wife devolves upon the husband only when she can be termed his kin (Lev. 21, 2). The betrothed woman does not come in this category and the divorced wife has lost that status (cf. Sanh. 28b, Sonc. ed., p. 171). See also Yeb. 22a (Sonc. ed., p. 132), 29b (Sonc. ed., p. 183). For his divorced wife, although he had children by her, he does not mourn, grieve, or [if a kohen] defile himself.

“A Cohen’s daughter may defile herself for the dead.” Rebbi Dosa from Malḥiyya, Rebbi Aḥa in the name of Rebbi Eleazar: A Cohen’s daughter is permitted to leave the Land²¹⁷A Cohen is prohibited from defiling himself in the impurity of the dead, Lev. 21:1–4. By rabbinic decree, a Cohen is forbidden to leave the Land of Israel since the other countries, even disregarding the biblical impurity inherent in them, might be full of unrecognized graves so that the Cohen would automatically incur at least the doubt of contamination by a grave.. What is the reason? “Say to the Cohanim²¹⁸Lev. 21:2: “Say to the Cohanim, the sons of Aaron.” The prohibitions in this paragraph inherently concern only the males of the family. This is explicit in Sifra Emor, Introduction; alluded to in Babli, 23b..” Not to the daughters of Cohanim. If it were not so, what would he say? Because she is included in the decree, she cannot leave. Why should she not be included in the decree and be forbidden to leave²¹⁹Since the prohibition is rabbinic anyhow, how can the extent of the prohibition be measured by biblical standards? It is unlikely that the prohibition was known before the war of Bar Kokhba. We find king Yannai outside the Land, but he was a Sadducee and opposed to rabbinic prohibitions. But it is reported that R. Eleazar ben Azariah, a Cohen, descendant of Ezra in the tenth generation, went to Rome.? If you say so, you push aside the paragraph on impurities²²⁰Since rabbinic decrees are גדירה, fences around the Law, they should not prohibit what is explicitly permitted in the Pentateuch..
