Apostate prophet exposes polygamy; biblical multimarriages?

In answer to the video "Walking Away From Islam"

Mosaic Law made no prohibition on male premarital or extramarital sexual activity so long as the women involved were not the property of another Jew. A Jewish male could acquire as many wives as he could afford, and also avail himself of the services of concubines, female war captives of any age regardless of them being married or not Deut21:10-17,Num31:17-18.

This was the case with the most eminent of their religious figures, including Abraham, Moses, David or the wise king Solomon who were all polygamists, down to the regular members of society, including the priestly clan of the Levites 1Sam1:1-2.

Jacob counted 2 living sisters among his wives, which is against Torah law hence the various rabbinic explanations to the problem of having the father of the Jewish nation violating a future prohibition. Torah sets no limits to the number of wives Ex21:10,Deut21:15 although it vaguely warns Israelite rulers (not common people) against having "too many" wives Deut17:17. Some Jewish comentators have argued, based on rabbinical discussions in the Talmud, that the maximum number of wives in all cases shouldnt exceed 18. Polygamy is at the foundation of the Jewish nation. It even was and is still seen as a good deed, the best fulfillement of the eternally binding command to

"be fruitful and multiply",

so much so that it can hasten the messianic age. It was practiced throughout the Talmudic period, with the legislation saying that a man can have as many wives as are willing to marry him (as long as he can support them) without any hint to it being an immoral or abnormal practice. It was such a well established part of the social system that Mosaic law is not even critical of it.

We find only certain regulations with respect to it but that were not practiced in reality as seen with David and Solomon's cases whose prophethood and kingship are never questionned despite their "transgressions". It was not until the 10th century and the rabbinic ban upon it specifically on the Ashkenazic fringe, that made the issue controversial. If it wasnt a widespread practice, there would be no need to issue such a forceful amendment. Jews needed to accomodate for the Christian host nations that forbade the practice, fearing further isolation and persecutions from a people that already resented them.

Contrary to their other host nations, namely the Muslims, Christian tradition isnt a continuation of Jewish tradition but of Greek and Roman pagan traditions, society and morality. Ancient Greeks, including the likes of Plato and Socrates, the supposedly great philosophers saw homosexuality, which they practiced and lauded, as the highest symbol of manhood. Women were inconvenient breeders, not ideal partners. Although Christianity somewhat discouraged homosexuality, it adopted this Greek attitude towards women and normal relations between men and women, adding the whole negative, evil spin to it.

Christians try interpreting the polygamy verses as if it is talking of marriage after divorce or death of a wife which is absurd since it says such marriage should not lead one to diminish any of the wife's conjugal rights, ie the first wife's of which the preceding verse clearly speaks of. Jesus does not oppose polygamy and even uses it in his parable to make his point about readiness for the kingdom Matt25. This was the perfect occasion for him to oppose it or criticize it, but doesnt at all. He features it, meaning giving it tacit approval. From this noninterference attitude Luther, as late as the 16th century, arrived at the conclusion that he could not forbid the taking of more than one wife.

The Quran clearly alludes to the fact that as per the norms of human nature, the real benefits and advantages of the institution of family manifest themselves in a monogamous family. And despite fully endorsing, and not limiting polygamy neither quantitatively nor contextualy, the HB too speaks of the preference for a man to be united with a single wife Gen2:24.

As a side issue, one might ask why the regulation doesnt apply to women as well (polyandry). Aside from the basic issues of uncertain descendancy, a woman becomes undisposed to satisfy the most basic physical or sexual needs of her multiple husbands. IT is the case during her menstrual period or while pregnant. Also, from a strict biological viewpoint, a woman can only carry and conceive one child at a time and from one man only, for nine months before she can conceive another. A man on the other hand can beget a child every time he cohabits with a woman. Polyandry opposes these very elementary socio-biological issues. That is why it is practiced by very few societies that seek to limit population growth, with a purely materialistic outlook. For example, polyandry in the Himalayan mountains is related to the scarcity of land. The marriage of all brothers in a family to the same wife allows family land to remain intact and undivided.
