Do not be sexually intimate with a promiscuous woman without the consecration of marriage.
“There shall be no promiscuous women amongst the daughters of Israel” Devarim 23:18
The term “promiscuous woman” means an unmarried woman who has abandoned herself to harlotry, or her farther has given her over for sexual relations without the purpose of marriage,
Or her father had submitted her to harlotry.
If someone is sexually intimate with a “promiscuous woman” for immoral purposes, without being married, both violate this prohibition.
This applies in all places at all times.
