The Tanakh demolishes the “fake Jews” claim by showing that the covenant people were founded, expanded, and sustained by outsiders who chose faithfulness to Hashem and His Torah. Today’s detractors would brand these figures “fake Jews” with laughable absurdity.
Avram was a Chaldean idol-worshiper from Ur (Josh 24:2), a total foreigner with no Jewish blood. Yet Hashem called him, renamed him Avraham, and made him the nation’s father. All four Matriarchs, Sarah, Rivkah, Rachel, and Leah, were born Arameans outside the covenant (Gen 11:29, 25:20, 29:16–18). By bloodline logic, Israel’s mothers were “fake Jews,” which is patently ridiculous.
The Mixed Multitude, Egyptians and others, saw the plagues, feared Hashem, fled with Israel, stood at Sinai, and declared “Na’aseh v’nishma” alongside the tribes (Ex 12:38; 24:7; Num 15:15). Detractors would call these miracle-witnesses “fake” for lacking Israelite DNA. Yet Torah mandates “one statute for you and the stranger.”
Rahab, a Canaanite from cursed Jericho, confessed “Hashem your God is God in heaven and earth,” hid the spies, and joined Judah (Josh 2:11, 6:25). Detractors would label her “fake,” yet she is Israel’s heroine.
Ruth the Moabite, from a nation Torah bars (Deut 23:4), declared “Your people my people, your God my God,” kept the mitzvot she barely knew, and became David’s great-grandmother. She entered the line of the promised Mashiach ben David (Ruth 1:16, 4:13–22; Isa 11:1, Jer 23:5). To call Ruth “fake” mocks Israel’s future redeemer.
After Purim, countless Persians “became Jews” from awe at Hashem’s deliverance (Est 8:17), no genealogy, just covenant loyalty. Detractors would sneer, yet the Megillah celebrates them.
Moses surely triple-checked the entire Torah for DNA requirements and found none. The ger joins by accepting the yoke of mitzvot, period. DNA tests are themselves anti-Torah, with zero basis for determining Jewishness. The Torah never demands a bloodline check, only covenant loyalty. Halakha even forbids asking a convert for credentials once accepted (Yevamot 47a–b; Shulchan Aruch YD 268:12). To do so is to “oppress the ger” (Lev 19:33).
From Avraham’s “Lech lecha” to every ger who immerses and says “Na’aseh v’nishma” today, we welcome all who join the Sinai covenant. No irrelevant DNA test required. Exclude these covenant-keepers and you saw off the branch holding Avraham, the Matriarchs, the erev rav, Rahab, Ruth, and the Persians. You leave a racial fantasy the Tanakh never demands and repeatedly refutes.
