וְכָל־הַנֹּגֵ֗עַ בְּכֹל֙ אֲשֶׁ֣ר יִהְיֶ֣ה תַחְתָּ֔יו יִטְמָ֖א עַד־הָעָ֑רֶב וְהַנּוֹשֵׂ֣א אוֹתָ֔ם יְכַבֵּ֧ס בְּגָדָ֛יו וְרָחַ֥ץ בַּמַּ֖יִם וְטָמֵ֥א עַד־הָעָֽרֶב׃
Setiap orang yang menyentuh apa pun yang pernah berada di bawahnya menjadi najis sampai petang, dan orang yang mengangkat benda-benda itu harus mencuci pakaiannya dan mandi dengan air, dan ia tetap najis sampai petang.
Mishneh Torah, Reading the Shema
All who are ritually unclean are bound nevertheless to read the Shema; and, while still unclean, they recite the blessings that precede and succeed it, even if it is possible for them to get rid of their uncleanness, on the same day; as is the case with those who have touched a creeping thing, or touched a woman in the period of menstruation, or touched one who has a running issue, or the couch on which anyone of these has lain, etc. Ezra and his colleagues ordained that only one who had had an emission—as an exception to all unclean classes—may not read the words of the Torah till he has ritually bathed. This ordinance was not adopted universally. The majority of the community were unable to observe it, and it fell into desuetude. All Israelites have accordingly had the custom to read the Torah and recite the Shema, notwithstanding that they had had emissions. For the words of the Torah are insusceptible of defilement, but remain always pure, as it is said, "Is it not thus, my words are like fire, saith the Lord" (Jeremiah 23:29). Even as fire is incapable of being defiled, so the words of the Torah are insusceptible of defilement, but keep their purity forever.
