וַאֲשֶׁ֛ר לֹא־נִתֵּ֥ן בְּנֹתֵ֖ינוּ לְעַמֵּ֣י הָאָ֑רֶץ וְאֶת־בְּנֹ֣תֵיהֶ֔ם לֹ֥א נִקַּ֖ח לְבָנֵֽינוּ׃
Asimismo, que si los pueblos de la tierra trajesen á vender mercaderías y comestibles en día de sábado, nada tomaríamos de ellos en sábado, ni en día santificado; y que dejaríamos el año séptimo, con remisión de toda deuda.
Mishneh Torah, Forbidden Intercourse
If a Jewish person sleeps with a non-Jew in the way of married people, they receive biblically ordained lashes, as it says “You shall not intermarry with them: do not give your daughter to their sons or take their daughters for your sons.” (Deuteronomy 7:3) The same law is true concerning the seven nations of the land of Canaan and all other nations. This is also explained by Ezra, “We will not give our daughters in marriage to the peoples of the land, or take their daughters for our sons.” (Nehemiah 10:31)
