A little tweaking: the author mistakes Jews with Hebrews. Jews are descended from the Kingdom of Judah, the southern state. the whole of the people would be called Hebrews, I suspect because Abraham’s grandfather’s name was Ever, which has the same root consonants as Ivri, Hebrew for Hebrew.
The Assyrians are assumed to be Semites, while the Scythians are assumed to be Indo-European, perhaps Aryans, like the Persians and the Turks. Assyrians were not Scythians.
Ancient Syria was ruled and populated by Arameans, another Semitic people.
Abraham's grandfather was Nahor. He had a more remote ancestor named Eber, six generations back.
The Scythians and Persians spoke Iranian languages of the Indo-European language family, which were related to the languages brought into India by the so-called Aryans. The Turkic languages are completely unrelated (they are distantly related to Mongolian).
