I understand historians to invent a new history in every age because they have to justify the sins of the present with the events of the past. They come up with a lot of stories for the past, because that's the only way they can prove the territorial claims, the legitimacy of atrocities committed, etc. Every Scripture other than the Quran fell into this error, but we were not innocent either, creating many Hadith (sayings attributed to the prophet) that he (peace be upon him) did not even dream of. These are facts.
However, it is also a fact that there are parts in the Scriptures that the politics did not rewrite because there was no interest to do that. Yet parables dealing with hardness of heart and sins, are in many cases more important than the whereabout of the boundaries. If people would draw a lesson from their sins and their hearts would soften, it doesn't matter if there is a border at all? Hold on now. The Quran does not cite the stories of Jews as counter-examples (so, I mean the children of Israel, not Moses and his followers!), saying that Jews are so bad and sneaky! These are the misinterpretations of today. Only the prophecies deal negatively in the eschatology of Islam about the raise of Jerusalem before the Last Day. However, when the Quran was revealed, the Jews had been living in a diaspora for 600 years, all over the world. They were not in a position to be "bad". The Quran brings up their stories as a counter-example, because you are the "bad" dear reader, whoever you are! If you stay that way, you will suffer from the similar destiny like them! After all, is the Quran universal or not? That is the point of the idea. If you weren't stone-hearted, sneaky, what would be the sense of coming up with the thousands of years of sins of the Jews? I know, in the age of the Prophet (peace be upon him), the Jews of Medina were sources of much trouble. But this is the problem of the Prophet and the Jews of Medina, we have nothing to do with it. The Quran does not want you to copy the example of a micro-community, but to draw conclusions from what the micro-community has gone through. The life of the Prophet (peace be upon him) and his responses to the social, religious issues in the circumstances of the age is a pattern for all of us. We have a lot to learn from him that we need to adapt to our own age. The story in the Bible (or call it Torah, which is confirmed below by the Quran, was not revealed first to the Muslims but to the Jews at that time! Allah (SWT) merely confirms it in the Quran! So, the critique is well ahead of Mohamed's time!
If we profess that the Quran is not for the Arabs but for humanity, then the time-journey to Medina only reinforces a much greater, more comprehensive thought. The sins in the sight of Allah are the same ever since the world was created. There is no Jewish and Arab sin, no Hungarian and Romanian sin. Here is an example on the hardness of heart that binds our thinking no matter who we are.

And one more thing. I do not share these thousands of years of thoughts in order to show off my classical knowledge, which is not worth a piece of shit today, but to support you for not to start exploring the sources of your troubles, because those have been articulated long ago in a very chiseled and deep way. I am just a mean that convey these thoughts.

Remember ye slew a man and fell into a dispute among yourselves as to the crime: But Allah was to bring forth what ye did hide. (Quran 2:72)

So We said: "Strike the (body) with a piece of the (heifer)." Thus Allah bringeth the dead to life and showeth you His Signs: Perchance ye may understand. (Quran 2:73)

When a body of slain man was found in a field and the slayer was not known, a heifer had to be beheaded and the elders of the city next to the slain's man domicile had to wash their hands over the heifer and say that they neither did the deed and saw it done, thus clearing themselves from the blood-guilt. When heifer was sacrificed God by a miracle disclosed the guilty person. A portion of the sacrificed heifer was ordered to be placed on the corpse which came to life and disclosed the whole story of the crime. Deuteronomy 21:1-9: "If someone is found slain, lying in a field in the land the LORD your God is giving you to possess, and it is not known who the killer was,2 your elders and judges shall go out and measure the distance from the body to the neighboring towns. 3 Then the elders of the town nearest the body shall take a heifer that has never been worked and has never worn a yoke 4 and lead it down to a valley that has not been plowed or planted and where there is a flowing stream. There in the valley they are to break the heifer's neck. 5 The Levitical priests shall step forward, for the LORD your God has chosen them to minister and to pronounce blessingsin the name of the LORD and to decide all cases of dispute and assault.6 Then all the elders of the town nearest the body shall wash their handsover the heifer whose neck was broken in the valley, 7 and they shall declare: "Our hands did not shed this blood, nor did our eyes see it done. 8Accept this atonement for your people Israel, whom you have redeemed, LORD, and do not hold your people guilty of the blood of an innocent person." Then the bloodshed will be atoned for, 9 and you will have purged from yourselves the guilt of shedding innocent blood, since you have done what is right in the eyes of the LORD."

Thenceforth were your hearts hardened: They became like a rock and even worse in hardness. For among rocks there are some from which rivers gush forth; others there are which when split asunder send forth water; and others which sink for fear of Allah. And Allah is not unmindful of what ye do. (Quran 2:74)

A wonderful poetical allegory in order to decribe that even a rock which is the hardest material in our notion can obey and turn to life and motion giving creatur. Even if our heart is hard as a stone with prostration, surrender His will our attributes can turn towards life and harmony.

And here it is! We've got to the hardness of heart. After offering the sacrifice of the slaughtered heifer, God brought the murdered man to life and he revealed the identity of the sinner, who until then denied his act. His heart has hardened in the sin. Statement of the Torah (Bible) and Quran together! It was needed a divine miracle for the sinner to confess. Neither repentance nor human inquiry led to that result.

According to the scholars of Sunnah, the causes of hardness of heart are the constant satiety, tempting environment, forgetting repentance, and excess of self-confidence. The Quran is adding the most important, the example of the rock, which either hardens and resists even more, or it shatters and a stream flow from it. Those, from which a stream comes forth symbolize a broken heart that is confessing and repentant. Water means life, so it carries life after repentance. The ones which hardens and resists drift, paint a picture of those whose sins embrace them and lead them to Hell:

Nay, those who seek gain in evil, and are girt round by their sins,- they are companions of the Fire: Therein shall they abide (Forever). (Quran 2:81)
