Genesis 12:7 "And the Lord appeared unto Abram, and said, Unto thy seed will I give this land:"
Galatians 3:16 "The promises were spoken to Abraham and to his seed. Scripture does not say “and to seeds,” meaning many people, but “and to your seed,” meaning one person, who is Christ."
And for your further consideration:
Galatians 3:28-29 28 There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. 29 If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.
The United States of America, too.
That in itself does not settle history and heritage
What UNESCO had said, is that the Jews had no connection to the Holy Land nor to the Temple. Simply false on historic grounds. The said the whole heritage of the place was exclusively Arab, and that is false on historical grounds as well.
What Pope Francis said, is "The people of Israel, who from Egypt, where they were enslaved, walked through the desert for forty years until they reached the land promised by God."
Nobody has refuted that statement.
