Leviticus 10:29

Do not prostitute thy daughter, induce her to permit her body to he used for immoral purposes, to cause her to be a whore, a sin which profanes the body in the most specific and emphatic sense, lest the land fall to whoredom, and the land become full of wickedness, full of abominable deeds. The reference is probably to religious immorality, as it was joined with many idolatrous worships and is to this day, in which women voluntarily abandoned their chastity as priestesses of the idol.
