משנה: מַמְזֵר פּוֹסֵל וּמַאֲכִיל. בְּאֵי זֶה צַד בַּת יִשְׂרָאֵל לַכֹּהֵן בַּת כֹּהֵן לְיִשְׂרָאֵל וְיָֽלְדָה מִמֶּנּוּ בַת וְהָֽלְכָה הַבַּת וְנִשֵּׂאת לְעֶבֶד אוֹ לְנָכְרִי וְיָֽלְדָה מִמֶּנּוּ בֵּן הֲרֵי זֶה מַמְזֵר. הָיְתָה אֵם אִמּוֹ בַּת יִשְׂרָאֵל לַכֹּהֵן תֹּאכַל בַּתְּרוּמָה בַּת כֹּהֵן לְיִשְׂרָאֵל לֹא תֹאכַל בַּתְּרוּמָה. MISHNAH: A bastard disables and enables to eat. How is this? A daughter of an Israel [married] to a Cohen [or] the daughter of a Cohen [married] to an Israel had a daughter from him. If the daughter went and married a slave or a Gentile and had a son from him, that is a bastard132In practice, he is an unblemished Jew.. If his mother’s mother was a daughter of an Israel [married] to a Cohen, she can eat heave133.If the grandmother’s husband and her daughter had died, the grandson is descended from a Cohen and keeps his grandmother in the priestly clan., the daughter of a Cohen [married] to an Israel cannot eat heave134If the grandmother’s husband and her daughter had died, the grandson is descended from an Israel and keeps his grandmother out of the priestly clan..
הלכה: מַמְזֵר פּוֹסֵל כול׳. לֵית הָדָא פְלִיגָא עַל רַב. דְּרַב אָמַר. גּוֹי וְעֶבֶד שֶׁבָּא עַל בַּת יִשְׂרָאֵל הַװְלָד כָּשֵׁר. פָּתַר לָהּ בְּגוֹי פָּסוּל וּבְעֶבֶד פָּסוּל. HALAKHAH: “A bastard disables,” etc. Does that not disagree with Rav, since Rav said that if a Gentile or a slave has intercourse with a Jewish woman, the child is acceptable. Explain it that the Gentile disables and the slave disables135While the Mishnah speaks of a bastard, the interpretation following the current practice is that both the daughter and the grandchild become disabled for the priesthood; cf. Halakhah 4:15. The Babli, 70a, simply states that the Mishnah either follows R. Aqiba or that Rebbi holds that the grandchild is a bastard by rabbinic standards since there is a general biblical prohibition of sexual relations with a person whom one could not marry, Deut. 23:18..
