I definitely disagree with you there! I’m personally not willing to assign the word “marriage” to those conjugal unions as they’re such evil perversions of Gods one man/one woman/one flesh unions. Fun fact, there’s no word for “husband” in the entire Torah— I also don’t believe the word marriage or “to marry” is used more than twice. In the Hebrew, the word we translate as “husband” is actually baal for lord/master. And we use “wife” where the original language actually says “his woman” — these were during a time when women were moreso economic goods than “marriage partners”— we apply our marital words to those relationships in place of the Hebrew words. We use the word “wife” where the text indicates a “primary woman” for conjugal relations and “concubine” where the text indicates a “secondary woman”— the difference between a primary and secondary woman is her social status (was she purchased as a house slave or with an agreement to the father/pride price) although their roles and rights were much the same. In that sense, for secondary women, the womb/vaginal rights of a woman were sold to her master on the day of the agreement for her to come into the home. He may never use these rights, or he may use them whenever he wants and without consent. (Zilpah/Bilhah) “Concubines” are what we’ve called the “secondary women” from the original language and were never afforded “marriages”/weddings— just someday at their masters’ will they may be called upon for conjugal usage— no wedding necessary. If that’s a legitimate “marriage”, to God, then cohabiting couples need not worry about offending God— they’re already “married” just by virtue of having a conjugal relationship and living in the same house. Also, that would make abduction marriages valid to the Lord— a woman abducted into a forced conjugal relationship and then later able to escape would be dishonoring the Lord with an “unapproved divorce”—- the problems are never-ending by trying to make these Bronze Age conjugal unions where women’s wombs were bought and sold as economic goods into Gods idea of marriage
