עַל־דְּבַ֞ר אֲשֶׁ֨ר לֹא־קִדְּמ֤וּ אֶתְכֶם֙ בַּלֶּ֣חֶם וּבַמַּ֔יִם בַּדֶּ֖רֶךְ בְּצֵאתְכֶ֣ם מִמִּצְרָ֑יִם וַאֲשֶׁר֩ שָׂכַ֨ר עָלֶ֜יךָ אֶת־בִּלְעָ֣ם בֶּן־בְּע֗וֹר מִפְּת֛וֹר אֲרַ֥ם נַהֲרַ֖יִם לְקַֽלְלֶֽךָּ׃
Por cuanto no os salieron á recibir con pan y agua al camino, cuando salisteis de Egipto; y porque alquiló contra ti á Balaam hijo de Beor de Pethor de Mesopotamia de Siria, para que te maldijese.
Mishnah Yevamot
An Ammonite and a Moabite are forbidden [to enter into the congregation of the Lord] and their prohibition is for ever. However, their women are permitted at once. An Egyptian and an Edomite are forbidden only until the third generation, whether they are males or females. Rabbi Shimon permits their women immediately. Said Rabbi Shimon: This is a kal vehomer: if where the males are forbidden for all time the females are permitted immediately, where the males are forbidden only until the third generation how much more should the females be permitted immediately. They said to him: If this is a halakhah, we shall accept it; but if it is only a logical reference, there is a refutation. He replied: This is not so, I am in fact saying a halakhah. Mamzerim and nethinim are forbidden, and their prohibition is forever, whether they be males or females.
