The Khazar actual homeland pre circa 600 BC, was the land immediately south of Judah, called EDOM.
The reason they wanted to occupy Judah, was because of Isaacs blessing to Esau, where he said, Esau's descendants will always be the servant of his brother Jacobs descendants, until by the sword they would remove the yoke of Jacob from them.
This event occurred during the years 600 BC and 30 AD, when the Edomites conquered a Judah which had been soundly defeated by Babylon, occupied it and rebuilt Solomons Temple, installing themselves as the Pharisees, Scribes, Sadducees and Lawyers over the Temple, Jerusalem and Judah itself.
Israel is not the Kazarian homeland, but simply just another land they stole.
Yes, they lie, steal, kill, covet and disobey all the other commandments. Always have, always will.
