Levítico 18

No te acuestes con una mujer durante su menstruación. Ella es impura durante ese tiempo.

Y no llegarás á la mujer en el apartamiento de su inmundicia, para descubrir su desnudez.

Also thou shalt not approach unto a woman to uncover her nakedness, as long as she is put apart for her uncleanness.

“‘You shall not approach a woman to uncover her nakedness, as long as she is impure by her uncleanness.
