First, the following verse means only that salvation is not a Jews-only thing. Whichever Anti Semite first used this verse to deny Jews our ethnicity and our heritage owes us an apology:
"[T]here is neither Jew nor Gentile, neither slave nor freeman, neither male nor female; for in union with the Messiah Yeshua, you are all one."
That verse simply means that everyone gets equal treatment in terms of that we are not better or worse than each other. All Jews, gentiles, slaves, free persons, men, women, and other persons in the Messiah Yeshua are sinners and have been redeemed by Yeshua the Messiah. Secondly:
"8 These are the names of Isra'el's children who came into Egypt, Ya'akov and his sons: Re'uven Ya'akov's firstborn; 9 and the sons of Re'uven - Hanokh, Pallu, Hetzron and Karmi. 10 The sons of Shim'on: Y'mu'el, Yamin, Ohad, Yakhin, Tzochar and Sha'ul the son of a Kena'ani woman. 11 The sons of Levi: Gershon, K'hat and M'rari.12 The sons of Y'hudah: 'Er, Onan, Shelah, Peretz and Zerach; but 'Er and Onan died in the land of Kena'an. The sons of Peretz were Hetzron and Hamul. 13 The sons of Yissakhar: Tola, Puvah, Yov and Shimron. 14 The sons of Z'vulun: Sered, Elon and Yachle'el. 15 These were the children of Le'ah whom she bore to Ya'akov in Paddan-Aram, with his daughter Dinah. In sum, his sons and daughters numbered thirty-three. 16 The sons of Gad: Tzifyon, Haggi, Shuni, Etzbon, 'Eri, Arodi and Ar'eli. 17 The children of Asher: Yimnah, Yishvah, Yishvi, B'ri'ah, and their sister Serach. The sons of B'ri'ah were Hever and Malki'el. 18 These were the children of Zilpah, whom Lavan gave to Le'ah his daughter; she bore them to Ya'akov - sixteen people. 19 The sons of Rachel Ya'akov's wife: Yosef and Binyamin. 20 To Yosef in the land of Egypt were born M'nasheh and Efrayim, whom Osnat the daughter of Poti-Fera priest of On bore to him. 21 The sons of Binyamin: Bela, Bekher, Ashbel, Gera, Na'aman, Echi, Rosh, Mupim, Hupim and Ard."
Let's break this down for some of you: "Sha'ul the son of a Kena'ani woman", an eighth Patrilineally Jewish. Same with " 'Er, Onan, Shelah, Peretz and Zerach"; and "M'nasheh and Efrayim, whom Osnat the daughter of Poti-Fera priest of On bore to him". Later, M'nashe takes a Aramit concubine:
The descendants of M'nasheh: his concubine the woman from Aram bore Makhir the father of Gil'ad; Asri'el [Gil'ad's son] was descended from her. 15 Makhir's wife was from the families of Hupim and Shupim, and his sister's name was Ma'akhah. M'nasheh's second son was Tz'lof'chad, and Tz'lof'chad had daughters. 16 Ma'akhah the wife of Makhir bore a son whom she named Peresh, the name of his brother was Sheresh, and his sons were Ulam and Rekem. 17The son of Ulam was B'dan. These were the descendants of Gil'ad the son of Makhir the son of M'nasheh.
Makhir was a 1/16th Patrilineally Jewish.
To conclude, you Anti Semites and Anti Missionaries need to grow up and quit trying to deny especially Messianic Jews our Jewish heritage.
