Leviticus 18:19 forbids a man from having sexual relations with his wife during the period when she is ritually unclean, which under Israel’s law meant during her menstrual period. The verse belongs to a set of purity laws that God gave Israel through Moses, and it is spoken by the LORD to the people of Israel, speaking through Moses, as part of His instructions on holy living.
“‘You shall not approach a woman to uncover her nakedness, as long as she is impure by her uncleanness.

What Leviticus 18:19 Means
The phrase “you shall not approach a woman to uncover her nakedness” is a Hebrew idiom for sexual relations. The verse is not describing violence or the general mistreatment of women. It addresses the physical intimacy of marriage and sets a time-based limit on it. The phrase “as long as she is impure by her uncleanness” points to the woman’s monthly cycle, which the Law treated as a period of ritual impurity requiring a set time of separation and cleansing.
The verse does not state that the woman is sinful, dirty, or shameful because of her body. Under the Law, ritual uncleanness was a status that affected what a person could touch or do in worship, not a moral failing. The verse also does not give a reason for the rule in full. Scripture ties these purity laws to Israel’s holiness before the LORD, a theme that runs through the whole book. What the verse promises is a clear boundary, not a comment on the value of the woman or the marriage itself.
The Context of Leviticus 18:19
Leviticus is the third book of the Torah, traditionally attributed to Moses, and it was given to the priests and the people of Israel as they prepared to live as God’s holy nation. Chapter 18 opens by telling Israel not to imitate the practices of Egypt and Canaan, and then it lists forbidden unions and sexual acts. The surrounding verses, from verse 16 through verse 22, form a sequence of prohibitions about family relationships, adultery, and worship.
Because verse 19 sits among these laws, it reads as part of a larger picture of what separates Israel’s life from the surrounding nations. The purity of the marriage bed and the purity of the community before God go together in this chapter. Reading the verse alongside its neighbors helps you see that it is a guard around marriage and worship, not an isolated rule about bodily fluids.
