You can’t name an alternate nation, yet you persist in doubt?
How else can Yeshua have only been sent for the Lost Sheep of the House of Israel? The nations of Israel were all that the apostles ministered to, and their migration north westerly is well established.
One only has to think clearly. Yeshua didn’t just come for the synagogues along the Mediterranean, those people migrated and populated Europe, fulfilling the promises to Abraham.
ES, when you go through the promises to Abraham, Isaac and Jacob, you necessarily deal with the promises made to Ishmael and Esau. Nations came from them, too, and they are sometimes pretty small and pretty much known only in their era.
Manasseh’s portion of the promised land went almost to Damascus. It included the Golan. One of his descendants is said to have continued the line through an Aramean. Everything points to mixing with Syrians/Assyrians.
