All the blessings, covenants and blessings were to Jacobs descendants. They were Essa's descendants that is why they said they had never been in bondage to any man. The new covenant also is not for them. Hebrews 8:8. Read your history King of Judah John Hyrcanus conquered the Edomites 125 bc they what you know as Jews today. True Israel was sent into dispersion 600 years or more before that and never returned to Israel but migrated from the Assyrian captivity to all of Europe and made those nations in fulfillment of the promise to Abraham his seed would become many nations.
