Yes jotto,
YHWH Elohim chose a people, a people that would believe in & follow His Word that He calls His Messiah. Yeshua (Jesus) is the name of the flesh that the Word appeared to men in after Israel rejected Him as their sovereign. [1Sam 8:7] And from there is was all down hill because they chose to put the Word of YHWH 3rd after the laws that they made & the traditions of Baal they had adopted. [2Kg 17]
So to set the record straight, Israel was a mixed multitude of the sons of Jacob and many of the nations who left Egypt with the sons of Jacob. Therefore, Israel is neither Jew nor Gentile, it is a people who believe in the living Word of Elohim that has been from the beginning of time. Even your Talmud (man-made law of the unbelieving Pharisees) admits this fact, that the Messiah has been from the beginning & it was the Messiah in Spirit who delivered Israel out of Egypt... from Sanhedrin, Chapter 11 ....
“The days of Messiah shall endure as long as long as from creation until now, as it is written...”
“The days of Messiah shall be 7000 years, as it is written, and the bridegroom rejoiceth over the bride, so shall they Elohim (God) rejoice over thee...”
The Father CHOSE His Messiah & all who believe in His Messiah are Israel, DNA & religion need not apply. Which is why it is written that He will once again, gather, purge the rebels, and ONLY the Israel of Messiah will enter into His reign. [Eze 20]
Shalom
“The righteous of all nations have a share in the World to Come.”
