A man is naturally polygamous therfore polygamy is divine and Biblical and this is the will of God.This is the cure for single ladie.

You're using Boolean AND table combinations for this reasoning. For such a logical combination result to be True, *all* contributory assumptions must be pairwise True.

Assumption 1: Man is naturally polygamous.
This is debatable. If we think Man is like some other mammals, multiple females per male might be defendable. If we think Man is like other social animals (insects - e.g. ants, termites, bees, etc.) then multiple males per female might be defendable. Some mammal and bird species are monogamous. There is no one relationship common among all species.

Assumption 2: Polygamy is divine.
According to the Bible, God made one Man as the climax of His creation on the sixth day. Then, to make a companion for him, He made a Woman from one of the Man's ribs. That's one of each, no more - male and female. Polygamy requires more than one of one of the sexes. So, we fail the test for polygamy. Assumption 2 is FALSE.

Assumption 3: Polygamy is the will of God.
Biblical records are purportably the explanations that God gives to mankind about the reasons for our condition and His solution for bringing us back into favor. Since His record states one of each, Man and Woman, the assumption is FALSE.

Combination conclusion: No matter what Assumption 1 status becomes, the Assumptions 2 and 3 failures render the combination FALSE. [Only one of them being False would be sufficient for the combination to be False.]

No its not. you supposed to love the wife you have.. look in proverbs and ever heard of adam and eve?

Didn't someone come with a trick question to Jesus, about a woman who married seven men, marrying the next when the previous one died, and then he asked, "who is her real husband in the world to come?" Jesus replied that they would be like the angels and would not marry and be given in marriage. Jesus said that the Mosaic Law (Genesis to Deuteronomy) was eternal, and not a single dot or stroke (jot or tittle) would be removed from it; and whoever teaches and observes the Law is great in heaven, and whoever would do away with the least Law, would be least in heaven. And, I don't see anywhere where the Law prohibits more than one spouse. But the Law says that if you marry, you are responsible for all the obligations to your partner, even if you love someone else more; even if you marry someone you love more. What's wrong, is oppressing someone; lying; going back on your agreements -- and that also includes marriage agreements. If you were a shepherd, you needed a lot of children to watch the flocks day and night, so it made sense to have more than one wife, if you could afford to do so.

I think the idea is to treat everyone, including your spouse(s), with fairness, compassion, generosity, at all times, even if you no longer are in love with them. Because humans tend to be jealous and competitive, having only one spouse is easier on the pocketbook and emotions.

I do not see where a husband who has one wife and who treats her badly and unfairly, is better in the Creator's eyes than someone with two or three wives, who treats his wives with fairness and compassion and generosity.

Check out Gen 20:18... the reference to wife is singular, not plural.

You're right. But in Genesis 20:2, he took Sarah, possibly for a second wife for himself. Abimelech seems to be behaving with common sense, unlike Abraham who was not truthful at first about his wife Sarah. I can't figure out why Abraham wanted Sarah to be known as his sister, instead of his wife. But, maybe the lesson was that one spouse is better than two or more. I really don't know.

His son Isaac was monogamous; but neither Abraham nor Jacob were monogamous. Abraham married again at age 140 and had six more children. When Isaac first met Rebekah, they had sex in his late mother's tent that same day:

Genesis 24:67 And Isaac brought her into his mother Sarah's tent, and
took Rebekah, and she became his wife, and he loved her; and Isaac
was comforted after his mother's death.

I can't fault them for having sex so quickly; he was at least 37 years old. Since he was intent on this arranged marriage and so was his father, there was no problem.

All in all, I think it's safe to say that our Elohim does not forbid having more than one wife; but it definitely complicates things and it causes jealousy, at least sometimes. The worst problems seem to be with treachery, such as with David and Bathsheba (2 Samuel 11:5). David definitely went over the line and paid for it, though not with his life; but their child paid.

I wonder how Paul of Tarsus would explain Romans 13 to Bathsheba's husband Uriah, how "every soul should be subject
to the higher powers … For rulers are not a terror to good works … For [David] is the minister of God to you for good …" even as David plotted his death:

Romans 13:1 Let every soul be subject to the higher powers. For there is
no power but of God: the powers that be are ordained of God.
Romans 13:2 Whoever therefore resists the power, resists the
ordinance of God: and they that resist will receive to
themselves damnation.
Romans 13:3 For rulers are not a terror to good works, but to the evil.
Will you then not be afraid of the power? do that which is
good, and you will have praise of the same:
Romans 13:4 For he is the minister of God to you for good. But if you do
that which is evil, be afraid; for he bears not the sword in
vain: for he is the minister of God, a revenger to execute
wrath upon him that does evil.

This is the 'divine right of the king', which started with Constantine's desire to do away with the Law and Prophets and replace them with Nicaean doctrines that were foreign to all that came before, that gave the king unlimited power to overrule eternal ordinances of God (such as Saturday sabbath and Passover observance). Romans 13:1-7 was loved by kings for centuries afterwards, who could do as they pleased and fear neither man nor God; but that revision was not in place in David's time.

At this time, there is no Hebrew nation and Abraham has no children. Abimelech is representative of the other social groups of the day (pagan = Gentile). There was no recognized set of Hebrew Laws (handed over by God to the Hebrews).

Abraham was indeed a half-brother to Sarah, as well as her husband. If Abimelech decided he wanted Sarah permanently, then he would have to kill Abraham in order to possess her. If Abimelech understood Sarah to be Abraham's sister, then Abraham's life would be spared. Here, Abraham is showing his imperfect trust in God's promises, in an effort to stay alive... Now, read the passages which follow - where Abimelech notices that all his own wives' and concubines' wombs have been shut up when he is about to take Sarah sexually. Abimelech is pertified that his household will suffer because of Sarah. And, he chastises Abraham for it.
