The Land of Israel as we know it by its biblical name 'Knaan' was promised to the Great Patriarchs of the Hebrew People. First it was promised to Abraham in clear verses in the Torah in Genesis, secondly it was promised to Isaac his Son, and then to his Son Jacob who is called 'Israel' after he defeated the Angel as famously recorded in the Torah in Genesis. Thus the Land of Israel was called so after the greatest of the Patriarchs, Jacob aka, Israel. The Torah points out that the greatest of the three Patriarchs, was Jacob (Israel), because unlike Abraham who had a wicked son Ishmael and Isaac who had a wicked son Esau, all the Children of Jacob(Israel) were righteous. The Torah later records how Jacob (Israel) and his 12 Tribes (Sons) go down to Egypt and settle there and how they get enslaved by Pharaoh for more then 200 years. After the time that God had set for the duration of their exile comes to an end, the God of Israel performs earth shuttering and world shacking grand scale miracles to rescue them and free them and bring them back to their natural God Given Land, the Land of Israel.
In the great 10 Plagues the God of Israel shows Pharaoh and all other Egyptians and the entire world at large who is in charge and who is the True Owner and Ruler and King of the world. Without any shadow of any doubt, The clarity of God's existence becomes self evident when God performs all these great miracles that defy the laws of nature, and bring about the complete salvation of his people from the hands of a brutal dictator.
So at the end of this, Egypt is completely and utterly devastated and destroyed, and the Jewish people begin a remarkable journey of spirituality in the desert that prepares them to become the nation that will receive the oracles of the only true faith directly from God himself in a grand spectacle done in a manner of a National Revelation, where every single Jewish , men women and Child and also all the millions of non-Jews who joined them after they saw with their own eyes the grandeur of God's greatness, will together at once will witness how God reveals himself to them with great spectacles and sounds and thunders and will give them his written word , The Torah publicly without any intermediators.
Thus the Jewish people became a nation at that pivotal time when they received God's Torah and in unison the Jewish religion was born in that pivotal moment in human history. Unprecedented in all the religions of the world, Judaism stands out as the only religion that didn't begin from the preachings of one loner who claimed that God had spoke to him, like for example, Christianity and Islam solely base their foundations on one man's dreams. Judaism on the other hand, didn't completely believe in Moses' claim to be the prophet of god, until all of them together had experienced prophecy , only then when they saw with their own eyes and heard with their own ears God's glorious presence when he revealed himself to them and said in the Ten Commandments : " I am Hashem your Lord, that took you out from the land of Egypt from the house of slaves, Do not have other gods before me" only then they believed Moses' status as a True Prophet sent by God.
So it is written in the Torah with extreme accuracy and crystal clarity that the God of Israel had chosen the Jewish people and all converts to Judaism who joined the Jews all throughout the years as his Chosen People and a Holy nation and a Kingdom of Priests. To them the God of Israel had performed all the great miracles that are recorded in the Torah, to them and not to Muslims, not to Christians, and not to hindus, and not to anyone else for that matter.
And he decided to dwell inside them by instructing them to build for his name a Temple where he will dwell with them, in the holy of holies. With them he had made an Ever lasting covenant in mount Sinai, never to be broken, or changed under any circumstances, no matter what will happen this covenant which god had swore by his name will exist forever, and he will never change them with another people as god had said in the Torah clearly in the verse Numbers 23:19 : "God is not a man, that he should lie, nor a son of man, that he should change his mind. Does he speak and then not act? Does he promise and not fulfill?".
God himself tells us in the Torah that he is not a Man, for a man can change his mind, but god doesn't change his mind, therefore when he chose the Jewish People and made a covenant with them, it is an ever lasting one, not to bound to change under any circumstances. He also says in the Ten commandments never to attribute any kind of physicality to him, for He is all spiritual and has absolutely no physicality what so ever :" Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth". "Thou shalt not bow down thyself to them, nor serve them".
Clearly when Christians claim that Jesus is god they are in fact according to the standards of the Torah and of god himself are in fact worshipping idols for god had specifically said with the clearest possible words and terms to not do that, not to attribute any kind of physicality to him, for doing so is against the will of The God of Israel.
The Muslims on the other came up with this claim that the person who was taken to be offered as a sacrifice by Abraham was not Isaac as the Torah says and as God himself says, they believe that it was Ishmael. There are major critical problems with this Muslim invention:
God himself tells Abraham to send Ishmael and his mother away, for only Isaac will be the person that will be the line to continue the chain in bringing about the Nation of Israel to be the people to receive the Torah. The God of Israel saves the Jewish people, the children of Isaac, by performing for them amazing ground shaking miracles and bringing them to the foot of Mount Sinai to give them his most precious thing, his Torah. In fact Ishmael never is mentioned after his story in Genesis, and from Isaac the history of the Jewish people and how they were saved and all that they had went through is recorded. They are the Heroes of the Torah, and Ishmael is never mentioned anymore, for he was sent away. And the Children of Israel were saved from Pharaoh because their forefather Abraham passed the test and was willing to bring his beloved son Isaac (the father of Jacob) as a sacrifice before God. So there is absolutely no logical or rational justification to this Muslim invention that defies all common sense and wisdom, and was just invented by the first Muslims to somehow try to steal the Title of Israel from the Jewish people, and was only believed by the pagans of that time who knew no better, and had no tools to counter the first missionaries of Islam, who really didn't give any choice to anyone just like the first Christians, it was either accept their 'claims' or be killed, so much for free will or free choice.
So the Christians have a twisted understanding of what God is and what God is not, for anyone who has a true understanding of God will never ever blame another one that he killed god, because god is above all the physical things that govern physical things, like death. God can't be killed, and if he can then he can't be god, and one of the greatest evidence that Jesus was not god, is that he was killed, and bled to death. That's without even saying that he was a mortal, flesh and blood, and physical, born of a man and a woman. The mind can't bare, and the wisdom can't accept that the God of the universe who created heaven and earth and everything in between will be a product of a flesh and blood creature and travel through her worldly body and go through the dirt and stink that all kids have to go through. This is nothing but pure pagan belief, not so much different then all the other men made religions of the world who never went through the 'Truth Detector' of Judaism's 'National Revelation' where the God of the Universe himself reveals himself to his followers and no doubts can exist after that at all.
Said all of this since the Jewish people are the descendants of Abraham Isaac and Jacob the people that god had swore to them that he will give this land to them, therefore from this power and only from this ultimate power which is the will of god in this world, the land of Israel belongs to them.
For God had created heaven and earth and he can give and take from anyone to anyone as he sees fit for he is the master of all, and no one can tell him what to do. The god of Israel chose the Jewish people from all the peoples of the world and he made an everlasting covenant with them and he gave them the land of their forefathers forever and ever, and under his instruction they built there two great temples for his Name, and had great Kingdoms and civilizations that gave to humanity and influenced humanity like no other people in history.
