Understand god did permitted polygamy. Among other but why do people think its accept able now.
One man one woman - Monogamy This marriage "type" is what most people are familiar with. Genesis 2:24
One man, many women - Polygamy
Jacob had 2 wives and fathered 13 children. This is rarely spoken about when the subject of marriage and the bible is debated! Genesis 4:19
Levirate - Brother-in-law marriage
If a woman were to become a widow and had not given birth to a son, she would be required to have "relations" with her brother-in-law. Genesis 38:6-10
A man, a woman, and HER property If a woman was "married" and infertile, she could giver her property, her slave, to her husband as a wife. Genesis 16
A man, one or more wives, and some concubines
A man could have one or more wives and any number of concubines. In modern terms, one man, his wive(s), and one or more mistresses. Genesis 20:10
A soldier and his female captive
As with many wars, women become the property of the victor. And that is how it was in biblical times. Female captives were forced to submit to their male captors, usually by force, RAPE. Deuteronomy 21:11-14 and Numbers 31:1-18
A male rapist and the victim
If a man raped a woman and she wasn't married, she would be forced to marry him. A man could rape any woman that he liked and they would be considered married. The draw back? For the man OF COURSE! He could not divorce her!! Deuteronomy 22:28-29
A male and a female slave
An owner could order a female slave to "marry" a male slave without any input from the female.The consumation of this "union" usually involved rape. Exodus 21:4
Also I heard deut 21 it'snt about rape but on how a man has sex with the woman he is bethrol to.
