Could it be one of these?
--Polygynous Marriage
Probably the most common form of marriage in the bible, it is where a man has more than one wife
--Levirate Marriage
When a woman was widowed without a son, it became the responsibility of the brother-in-law or a close male relative to take her in and impregnate her. If the resulting child was a son, he would be considered the heir of her late husband. See Ruth, and the story of Onan (Gen. 38:6-10).
--A man, a woman and her property — a female slave
The famous “handmaiden” sketch, as preformed by Abraham (Gen. 16:1-6) and Jacob
--A man, one or more wives, and some concubines
The definition of a concubine varies from culture to culture, but they tended to be live-in mistresses. Concubines were tied to their “husband,” but had a lower status than a wife. Their children were not usually heirs, so they were safe outlets for sex without risking the line of succession. To see how badly a concubine could be treated, see the famous story of the Levite and his concubine (Judges 19:1-30).
--A male soldier and a female prisoner of war
Women could be taken as booty from a successful campaign and forced to become wives or concubines. Deuteronomy 21:11-14 describes the process.
--A male rapist and his victim
Deuteronomy 22:28-29 describes how an unmarried woman who had been raped must marry her attacker.
--A male and female slave
A female slave could be married to a male slave without consent, presumably to produce more slaves.
