The Exile as per Ezek.

The exile took place because of the iniquities and sins of the people.  They had begun the worship of alien Gods even in the sacred precincts of the Temple itself. The women amongst them had taken to the worship of the God Tammuz/Dummuzi a fertility God worshiped throughout the Near East. The chosen people of Yahweh had turned their backs upon and betrayed the Lord, their God who in turn abandoned them to their fate.    The result was the conquest of their land and the exile of its peoples.  The act of Yahweh’s leaving can be seen in Ezekiel’s vision of the wheeled chariot of God who had previously resided inside the holiest of holies within the temple of Jerusalem.  Ezekiel saw in his vision the chariot of Yahweh carring him away from his temple, his city and his people in stages until he had completely left them to their own fate.
But, Yahweh did not leave his people without hope.  He assured them through his Prophet that if they followed his directives and obeyed his laws he would make them his people again and be a God to them.  Yahweh promised a new shepherd the “one shepherd” to keep watch over his people a scion of the House of David who would rise up to rule over them in righteousness.  The image Ezekiel used to illustrate the rebirth of the people was as powerful and perhaps more compelling than that of the wheeled chariot.  Ezekiel used the image of himself preaching to a plain of bones.  These bones began to move and shake then appeared to coalesce into human skeletons.  These skeletons began to have flesh cover them and returned to life anew.  Ezekiel also prophesied that the Temple would be built again in the midst of the tribes of Israel and Yahweh would again reside within the sacred precincts of the Temple amongst his people.  Ezekiel went further to explain that the Dead Sea would be refreshed and purified and the land about would bloom.
