Frequently Asked Questions
Q: What does Leviticus 15:18 mean?
A: Leviticus 15:18 discusses the laws of ritual impurity (tumah) that occur after marital relations. According to Torah law, both the man and woman become ritually impure and must immerse in a mikveh (ritual bath) and wait until evening to become pure again. This is part of the Torah's detailed laws about purity and impurity.
Q: Why is immersion in water required after marital relations?
A: Immersion in a mikveh is required to restore ritual purity. The Torah teaches that certain natural bodily functions, including marital relations, create a temporary state of tumah (impurity). Immersion, followed by waiting until evening, allows a person to return to a state of taharah (purity) so they can engage in holy activities, such as prayer or Temple service.
Q: Does this law still apply today?
A: Yes, Orthodox Jewish couples still observe the laws of family purity (taharat hamishpacha), which include immersion in a mikveh after menstruation and marital relations. While the Temple is not standing, these laws remain important for spiritual purity and marital holiness. The details are outlined in Jewish law (halacha) and are practiced by observant Jews today.
Q: What can we learn from this verse?
A: This verse teaches that physical intimacy, while holy within marriage, also requires spiritual purification. The Torah elevates human relationships by setting boundaries and rituals that remind us of the sacredness of marriage. The mikveh serves as a way to renew spiritual connection after physical closeness.
Q: Why does the impurity last until evening?
A: The Torah designates that certain types of impurity last until evening (see also Leviticus 11, 14). Evening (nightfall) marks a transition in time, symbolizing renewal. Rashi explains that waiting until evening allows for a complete purification process, ensuring that one does not rush back into holy matters without proper preparation.
Understanding the Verse in Context
The verse (Vayikra 15:18) discusses the laws of tum'ah (ritual impurity) resulting from keri (emission of semen). This is part of a broader section in Parashat Metzora detailing various forms of tum'ah and their purification processes. The Torah emphasizes that both the man and woman involved in such an act become tamei (ritually impure) and require immersion in a mikveh (ritual bath) to regain purity.
Rashi's Commentary
Rashi (Vayikra 15:18) explains that the phrase "שִׁכְבַת־זָרַע" ("emission of semen") refers specifically to an act that results in the release of semen, whether through marital relations or otherwise. He notes that the impurity applies even if the act does not result in conception, as the focus is on the physical emission. Rashi further clarifies that the requirement to bathe in water refers to immersion in a mikveh, as derived from other verses in the Torah.
Rambam's Halachic Perspective
In Hilchot Mechusarei Kaparah (1:3), the Rambam codifies this law, stating that both the man and woman become tamei and must immerse in a mikveh. He emphasizes that this impurity is temporary, lasting only until evening (עַד־הָעָרֶב), after which they are permitted to enter the Temple or eat terumah (if applicable). The Rambam also connects this to the broader framework of taharah (ritual purity) required for spiritual elevation.
Midrashic Insights
The Midrash (Torat Kohanim 15:18) explores the deeper symbolism of this law. It suggests that the temporary impurity serves as a reminder of the physical and spiritual consequences of human intimacy, even within the sanctity of marriage. The requirement for immersion in water symbolizes a spiritual renewal, allowing the individuals to return to a state of holiness after engaging in a natural but physically impactful act.
Practical Implications in Jewish Law
Philosophical and Ethical Dimensions
The Sforno (Vayikra 15:18) highlights that this law teaches moderation and mindfulness in physical relationships. Even within the permitted framework of marriage, the Torah imposes a brief period of impurity to encourage reflection and spiritual realignment. This aligns with the broader Jewish value of sanctifying physical acts by infusing them with spiritual intentionality.
