According to many Christians, traditional biblical marriage is between one man and one woman, any other forms of marriage are "wrong".
In reality, there are eight types of "traditional marriage", all of which are mentioned in the bible, none of which are criticized.
01. Man and Woman (Nuclear) {Genesis 2:24}.
02. Man and Brother's Widow (Levirate) {Genesis 38:6-10} (A widow who had not given birth to a son was required to marry her brother in law. Wife was expected to submit sexually.)
03. Man, Wives, and Concubine (King Solomon, who had 300 wives, many were concubines)
04. Rapist and Victim {
Deuteronomy 22:28-29} (a virgin who was raped must marry her rapist, and the rapist had to pay 50
shekels of silver for property loss.)
05. Man, Woman, and Woman's property {Genesis 16} (if a woman owns female slaves, they become husbands wives.)
06. Male Soldier and Prisoner of War {
Numbers 31:1-18, Deuteronomy 21:11-14} (Under the command of Moses, Israelis killed everyone but virgin girls, who were taken as
spoils of war. Wives were expected to submit sexually.)
07. Man and Multiple Women (Polygamy)
08.
Male Slave and Female Slave {Exodus 21:4} (Owner could assign a wife to each of his male slaves. Wives were expected to submit sexually.)
