אַךְ־בְּ֠זֹאת יֵאֹ֨תוּ לָ֤נוּ הָאֲנָשִׁים֙ לָשֶׁ֣בֶת אִתָּ֔נוּ לִהְי֖וֹת לְעַ֣ם אֶחָ֑ד בְּהִמּ֥וֹל לָ֙נוּ֙ כָּל־זָכָ֔ר כַּאֲשֶׁ֖ר הֵ֥ם נִמֹּלִֽים׃
Mas con esta condición nos harán estos hombres el placer de habitar con nosotros, para que seamos un pueblo: si se circuncidare en nosotros todo varón, así como ellos son circuncidados.
Mishnah Zevachim
All sacrifices which became disqualified, before they were flayed, their hides do not belong to the priests. After they were flayed, their hides belong to the priests. Rabbi Hanina vice-chief of the priests said: Never in my life have I seen a hide go out to the place of burning. Rabbi Akiva said: we learn from his words that if one flays a firstling and it is found to be terefah, the priests have a right to its hide. But the sages say: “I have never seen” is not proof: rather, it [the hide] must go forth to the place of burning.
