Le Deutéronome 7:4 Références du Talmud : Jerusalem Talmud Yevamot

A slave woman: “The woman and her children shall belong to her owner.¹⁴⁰Ex. 18:4, speaking of the Jewish indentured servant who has to serve for six years. If the children he had during that time with a slave woman were his, they would have to be freed with him at the end of his servitude.” A Gentile woman. Rebbi Joḥanan said in the name of Rebbi Sineon ben Ioḥai, it is written¹⁴¹Deut. 7:3–4. Since only the masculine is used, “he will divert”, but not the feminine, it is concluded that the verse speaks only about the Gentile husband. Therefore, the child of the Jewish husband and the Gentile wife is not the husband’s child.
The parallel to this paragraph is in the Babli 23a.: “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.
