וְאָכְל֤וּ אֹתָם֙ אֲשֶׁ֣ר כֻּפַּ֣ר בָּהֶ֔ם לְמַלֵּ֥א אֶת־יָדָ֖ם לְקַדֵּ֣שׁ אֹתָ֑ם וְזָ֥ר לֹא־יֹאכַ֖ל כִּי־קֹ֥דֶשׁ הֵֽם׃
I niech jedzą oni to, czém spełniono rozgrzeszenie ich dla upełnomocnienia rąk ich, dla poświęcenia ich: postronny zaś jeść tego nie będzie, bo świętém jest.
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.
