Talmud for Numbers 1:18

¹⁴²Parallels in Qiddušin 3:14; Gen. rabba 7(3); Eccl. rabba 7:26; Bemidbar rabba, Tanḥuma, both Pesiqtot, to Ḥuqqat (Parah). Jacob from Kefar Naboraia went to Tyre. They came to ask him, may one circumcise the son of a Gentile woman¹⁴³The son of a Jewish father born on the Sabbath, converted at birth. on the Sabbath? He wanted to permit it from the verse¹⁴⁴Num. 1:18, which determines the clan by patrilinear descent. The principle is expressed in Mishnah Qiddušin 3:12: “If there is a possibility of marriage without sin, the child follows its father”, even if the parents are not married.: “They determined their genealogies for their families according to their fathers’ houses.” Rebbi Ḥaggai heard it and said, he shall come. They brought him in order to be whipped. He said to him, for what reason do you whip me? He said, from what is written¹⁴⁵Ezra 10:3: “Now we shall make a covenant for our God to expel all these [foreign] women and what was born to them, as counseled by the Lord, by those who fear the commandments of our God; it should be done according to the Torah”. As usual, the main point is the part not quoted.: “Now we shall make a covenant for our God”. He said, you want to whip me based on tradition¹⁴⁶“Tradition” is the name for the books of Prophets and Hagiographs which are not books of law. The most one can infer from a text of tradition is how Torah laws were handled in later times.? He said, “and it should be done according to the Torah.” He said to him, from which teaching? He said, from that which Rebbi Joḥanan said in the name of Rebbi Simeon ben Ioḥai, it is written: “You shall not conclude marriage with them”. And it is written: “For he will divert your son from after Me.” Your son from a Jewish woman is called your son; but your son from a Gentile woman is not called your son but her son. He said to him, whip your whipping, because it is good to impress¹⁴⁷To impress upon him the lesson he should not forget..
