The purpose of marriage is found in Genesis 2:18
Gods will for woman was to be a helpmate to the man in every way, mentally, spiritually, emotionally, socially and physically. She was also created to bare the generations to come. A woman was not greater or less than the man, but was his equal.
For any marriage to work one should study 2 Corinthians 6:14 be ye not unequally yoked together with non-believers for what fellowship hath righteous with unrighteous, and what communion has light with darkness. If you are a believer in Jesus Christ then you need to choose a mate that also believes in the faith of Christ.
#73 in the 613 Mosaic laws: Not to withhold food, clothing or conjugal rights from a wife (
Ex. 21:10)
According to the Torah and the Talmud, a man was permitted to marry more than one wife, but a woman could not marry more than one man. Although polygyny was permitted, it was never common. The Talmud never mentions any rabbi with more than one wife. Around 1000 C.E., Ashkenazic Jewry banned polygyny because of pressure from the predominant Christian culture. It continued to be permitted for Sephardic Jews in Islamic lands for many years. To the present day, Yemenite and Ethiopian Jews continue to practice polygyny; however, the modern state of Israel allows only one wife. Those who move to Israel with more than one wife are permitted to remain married to all of the existing wives, but cannot marry additional ones.
