וְאָכְל֤וּ אֹתָם֙ אֲשֶׁ֣ר כֻּפַּ֣ר בָּהֶ֔ם לְמַלֵּ֥א אֶת־יָדָ֖ם לְקַדֵּ֣שׁ אֹתָ֑ם וְזָ֥ר לֹא־יֹאכַ֖ל כִּי־קֹ֥דֶשׁ הֵֽם׃
Ils les mangeront ces mêmes offrandes qui les auront purifiés pour que s’accomplisse leur installation, pour qu’ils soient consacrés; un profane n’en pourra manger, car elles sont une chose sainte.
Mishnah Pesachim
An onen immerses [in a mikveh] and eats his pesah in the evening, but not [other] sacred food. One who hears about his dead [for the first time], and one who gathers the bones [of his dead relative] immerses and eats sacred food. A convert who converts on the eve of Pesah: Bet Shammai say: he immerses and eats his pesah in the evening. Bet Hillel say: anyone who separates from the foreskin is like one who separates from the grave.
