Old Testament allows monarchy

Deuteronomy 17 allows the monarchy and puts complete hold on the system called "king"

Watertight Constitution

Moses tries to structure this constitution as watertight as possible. For example in Deteuronomy 13 God says through Moses that if any prophet prophecies something which comes true and he insists the people to follow some other God, God tells not to follow such a man because through this man He is testing the people.
Christs existence in such a risky community was awful!

Annihilation of 7 nations

The brutality of annihilation of 7 nations is subdued in Deteuronomy 9, as God says "Do not say in your heart when the LORD your God has driven them out before you, ‘Because of my righteousness the LORD has brought me in to possess this land,’ but it is because of the wickedness of these nations that the LORD is dispossessing them before you. “It is not for your righteousness or for the uprightness of your heart that you are going to possess their land, but it is because of the wickedness of these nations that the LORD your God is driving them out before you, in order to confirm the oath which the LORD swore to your fathers, to Abraham, Isaac and Jacob.
Well now the question remains of judging the brutality of these 7 types of people!!! With what parameters they were judged? Who is to decide those parameters?
They were not even given the choice to think upon the ideology of sons of Israel. They were just annihilated not even given a chance to convert. Its brutal than colonization!!

Deuteronomy 8

In Deuteronomy 8 God says through Moses that the 40 years of difficulties which were brought upon the sons of Israel were brought with an intention of disciplining the people, like father disciplines his son.
Here the exat moral stand of Moses are very much clear. The moral stand is pretty simple. He wanted his people to live happily forever. And by happiness he didn't mean just exploiting pleasures out of life. He meant happiness in real sense or lets say he tried to meant and define the happiness for his people. He definitely tried to connect the state of being happiness with a sturdy conscience.
Just as Plato made the mistake while defining his Republic to put aside the poets from ideal society, so also Moses has his own mistakes.
The ideology he tried to state is definitely not the ideal human existence but in human history it surely could be considered as one of the well tried steps towards towards achieving the ideal human existence.
I think Christ was well aware of this well-tried step, thats why he didnt say a criticizing word against it.

7 nations for one

So once upon a time there existed people the Hittites and the Girgashites and the Amorites and the Canaanites and the Perizzites and the Hivites and the Jebusites.
God said that they are not fit to live there where they were living and he ordered that his people whom he called sons of Israel should live there for ever.
Here are thethings God ordered sons of Israel to do to these 7 nations:
"You shall tear down their altars, and smash their sacred pillars, and hew down their Asherim, and burn their graven images with fire"

No visual representation of God

General indian tendency can confer divinity to any object or person or creture. Snake, elephant, Cow, Sun... all have been conferred with some kind of divinity. 4th chapter of Detueronomy completely denies the representation of God in any visual format.
This visual representation was denied until the Christ's Time. From Christ that is after his cricifixion this ideology started having a visual representation in form of 'cross' and 'christ'. Though the community started having new visual aspirations but the former ones were and are not yet completely deleted. Still Yaweh is faceless.
For Indian mentality the former ordinance of not representing God in any visual format is and has always been quite difficult to accept. 'Christ' and 'cross' was more convinient and inevitable choice for Indian mentality. I wonder if Yaweh really exists for Indian christians!

Religious movement or political movement

The movement of 40 years in wilderness begins in Exodus. For any sane reader it seems a religious movement when it begins but near the end of book of Numbers it becomes very much clear that it is more a political movement than religious movement. It seems here very much true that societies are formed on the basis of common enemy.
God's contant allusion that he intends to create nation out of this community also signifies that it was more a political movement rather than religious movement.
Christ's work could be termed as religious movement because he challenged values rather than person/persons or any ruler. Moses felt the need to free jews from the bondages of Egyptians but Christ never felt the need to leberate jews from Romans.
