Levítico 15

The woman also with whom man shall lie with seed of copulation, they shall both bathe themselves in water, and be unclean until the even.

Y la mujer con quien el varón tuviera ayuntamiento de semen, ambos se lavarán con agua, y serán inmundos hasta la tarde.

If a man lies with a woman and there is an emission of semen, they shall both bathe themselves in water, and be unclean until the evening.
