Leviticus 15:18 (KJV)

What does Leviticus 15:18 mean?

Leviticus 15:18 says that when a man and a woman have sexual relations, both are required to bathe in water and are considered ritually unclean until evening. This instruction is about ritual purity, not moral wrongdoing, and sets out what to do after sexual activity according to ancient Israelite law.

In Leviticus, God is giving Moses laws for the Israelites about purity and daily life. This verse is part of a longer section explaining what makes a person ritually unclean and what steps to take afterward. The focus is on practical actions—bathing and waiting until evening—to restore ritual cleanliness, which was important for participation in community and worship.

The Hebrew behind Leviticus 15:18

• "Lie" (שָׁכַב, shakav): This word means to lie down, often used for sexual relations. Its use here is direct and physical, not metaphorical.
• "Seed" (זֶרַע, zera): This means seed or offspring, but in this context, it refers specifically to semen.
• "Copulation" (שִׁכְבַת, shikhvat): This word is related to lying down, emphasizing the physical act of sexual union.
• "Bathe" (רָחַץ, rachats): This means to wash or bathe, indicating a full washing with water, not just a symbolic act.
• "Unclean" (טָמֵא, tame): This word refers to ritual impurity, not physical dirtiness or sinfulness. It means the person cannot take part in certain religious activities until evening.
• "Even" (עֶרֶב, erev): This means evening, marking the end of the period of impurity.

Why Leviticus 15:18 matters

• Leviticus 15:18 clarifies that ritual impurity after sex is not about sin but about ceremonial status, which is reset by bathing and waiting until evening.
• This verse shows the practical, everyday nature of many Old Testament purity laws, which affected ordinary life and not just religious rituals.
• Understanding this verse helps make sense of the broader chapter, which deals with bodily discharges and their impact on ritual cleanliness, showing the interconnectedness of physical life and worship in ancient Israel.
