As long as she is put apart - See Clarke's note on Leviticus 15:24.

Also thou shalt not approach unto a woman to uncover her nakedness, as long as she is put (k) apart for her uncleanness.
(k) Or while she has her period.

Also thou shall not approach unto a woman,.... Not even a man to his own wife, and much less to another woman:
to uncover her nakedness, as long as she is put apart for her uncleanness; in her monthly courses; and the time of her separation from her husband on that account was seven days, Leviticus 15:19; if a man lay with a woman when in such circumstances, they were both to be cut off from their people, Leviticus 20:18; and such an action is reckoned among sins, and uncleanness of the worst sort, Ezekiel 22:10.

Prohibition of other kinds of unchastity and of unnatural crimes. - Leviticus 18:19 prohibits intercourse with a woman during her uncleanness. טמאה נדּת signifies the uncleanness of a woman's hemorrhage, whether menstruation or after childbirth, which is called in Leviticus 12:7; Leviticus 20:18, the fountain of bleeding. The guilty persons were both of them to be cut off from their nation according to Leviticus 20:18, i.e., to be punished with death.

As long as she is set apart - No not to thy own wife. This was not only a ceremonial pollution, but an immorality also, whence it is put amongst gross sins, Ezekiel 18:6. And therefore it is now unlawful under the gospel.
