When the Assyrians deported the Israelites, they did not call them Israelites, rather they referred to them as Khumri or Bit Khumri, after the "house of Omri" one of their notable kings. This word Khumri the Greeks transliterated as Kimmeroi, and the Romans followed, the result being the modern English Cimmerians.
“And I will set a sign among them, and I will send those that escape of them unto the Nations, to Tarshish, Pul, and Lud, that draw the bow, to Tubal, and Javan, to the isles afar off, that have not heard my fame, neither have seen my glory; and they shall declare my glory among the Nations.”
The children of Israel were to declare the glory of their God among the nations. Tarshish is the Japhethite nation in modern Spain. Pul is a word for Assyria after their king at the time (2 Kings 15:19, 1 Chronicles 5:26). Lud is Lydia in Anatolia, from whom the Etruscans of Italy also descended. Tubal is one Japhethite tribe inhabiting the region around the Black Sea at this time. Javan are the Japhethite Ionian Greeks. They too had many colonies, around the Black Sea, the Danube River Valley, and as far west as Marseilles, a city which the Phocians – a tribe of the Ionians from Phocis, a district in Greece – are credited with having founded. These are the nations which Israel was to be a “light” to, and they are all Genesis 10 Adamic nations. This is the context supplied by Isaiah. This is the “region of the Nations” of Matthew chapter 4. There is no universalism in the Bible once it is read in context. Not 200 years after the deportations during which Isaiah wrote, the children of Israel showed up in all of these places, from the Black Sea all the way to Iberia, modern Spain, and they were called Kimmerians and Saxons.
