Parasha Commentary

Prohibition Against Uncovering the Nakedness of a Father's Sister

The verse (Vayikra 18:12) prohibits uncovering the nakedness of one's father's sister, emphasizing that she is a close relative ("she'er avicha hi"). This prohibition is part of the broader framework of forbidden relationships (arayot) outlined in Parshat Acharei Mot.

Explanation from Rashi

Rashi explains that this prohibition applies equally to both the paternal and maternal aunts (father's sister and mother's sister, as mentioned in the following verse). The term "she'er" refers to a blood relative, and the Torah emphasizes the familial bond to reinforce the severity of the prohibition.

Halachic Implications (Rambam)

Rambam (Hilchot Issurei Bi'ah 2:6) codifies this prohibition as one of the biblical forbidden relationships. He clarifies that this applies whether the aunt is the father's full sister, half-sister (from the same father but different mother, or vice versa), or even if she was conceived from a forbidden relationship (e.g., if she were the product of an incestuous union).

Concept of She'er (Familial Connection)

The Talmud (Yevamot 54b) discusses the term "she'er" and explains that it denotes a close blood relationship, which creates a sacred bond that must not be violated. The prohibition extends beyond mere physical relations—it includes any behavior that could lead to inappropriate closeness.

Moral and Spiritual Dimensions (Midrash)

The Midrash (Torat Kohanim 18:12) teaches that these laws are not arbitrary restrictions but are meant to preserve the sanctity of family structure. Violating these boundaries undermines the moral fabric of society and damages the spiritual purity of the individual and the community.

Practical Applications

  • The prohibition applies in all circumstances, whether the aunt is married or unmarried.
  • It includes both paternal and maternal aunts, as derived from the broader context of the chapter.
  • The severity of the transgression is underscored by the punishment of karet (spiritual excision) for intentional violation.

Frequently Asked Questions

Q: What does Leviticus 18:12 mean when it says 'Thou shalt not uncover the nakedness of thy father’s sister'?
A: This verse prohibits intimate relations with one’s paternal aunt (father’s sister). The Torah considers this a forbidden relationship, as she is closely related through one’s father. Rashi explains that 'uncovering nakedness' refers to any form of prohibited intimacy, not just physical exposure.
Q: Why is it forbidden to marry or have relations with a father’s sister according to Jewish law?
A: The Torah lists specific forbidden relationships to maintain family purity and boundaries. A father’s sister is considered 'she’er basar' (close kin), and such unions could lead to moral and social disorder. The Rambam (Hilchos Issurei Biah 2:6) categorizes this as one of the arayos (forbidden relationships) with severe consequences.
Q: Does Leviticus 18:12 also apply to a mother’s sister?
A: No, this verse specifically addresses a father’s sister. However, Leviticus 18:13 separately prohibits relations with a mother’s sister. The Talmud (Yevamos 54b) clarifies that both paternal and maternal aunts are forbidden, but they are listed in different verses to emphasize their distinct prohibitions.
Q: How does this law apply in modern times?
A: The prohibition remains binding today as part of Torah law. Orthodox Judaism strictly upholds these marital restrictions, and someone who violates this would be transgressing a biblical commandment. Contemporary halachic authorities (like the Shulchan Aruch, Even HaEzer 15) reiterate these laws in detail.
Q: What is the deeper lesson behind this prohibition?
A: Beyond the legal aspect, this teaches the importance of respecting family boundaries and maintaining kedushah (holiness) in relationships. The Midrash (Vayikra Rabbah 23:9) connects these laws to Israel’s sanctity, as moral purity distinguishes the Jewish people.
