David and Solomon lived about 1000 BCE. And reading the Old Testament, you can see the trouble that multiple wives brought to a man: misery and jealousy between the women, strife between the children of different mothers, and having a bunch of wives didn’t stop David from committing adultery with Bathsheba...
the idea of one wife came as the Jewish people slowly came to realize that women were equal to men in dignity, and that polygamy lowered the dignity of women.
So by the time of Malachy, monogamy was accepted, and he insisted that divorce was hated by God.
By the time of Christ, monogamy was the Jewish custom, and at his time there was a big argument among the rabbis about divorce, if it should only be for adultery of the woman, or could it be allowed for lesser reasons. Christ said no divorce, although Paul did allow divorce for a Christian if the non Christian spouse would not allow the practice of religion.
And this is the idea, that women are more than chattel, that propelled the followers of the Judeo-Christian philosophy to become the rulers of the world.
