“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.
Isaiah 49:19 For thy waste and thy desolate places, and the land of thy destruction, shall even now be too narrow by reason of the inhabitants, and they that swallowed thee up shall be far away. 20 The children which thou shalt have, after thou hast lost the other, shall say again in thine ears, The place is too strait for me: give place to me that I may dwell.
This is talking about the nations which eventually descended from the children of Israel, that they would keep spreading out into the world. It describes the Saxon peoples of the past 2500 years through the colonial period.
