וְכָל־הַנֹּגֵ֖עַ בְּמִשְׁכָּבָ֑הּ יְכַבֵּ֧ס בְּגָדָ֛יו וְרָחַ֥ץ בַּמַּ֖יִם וְטָמֵ֥א עַד־הָעָֽרֶב׃
Setiap orang yang menyentuh tempat tidurnya harus mencuci pakaiannya dan mandi dengan air, dan ia tetap najis sampai petang.
Mishnah Chagigah
The garments of an am haaretz possess midras-impurity for Pharisees. The garments of Pharisees possess midras-impurity for those who eat terumah. The garments of those who eat terumah possess midras-impurity for [those who eat] sacred things. The garments of [those who eat] sacred things possess midras-impurity for [those who occupy themselves with the waters of] purification. Yose ben Yoezer was the most pious in the priesthood, yet his apron was [considered to possess] midras-impurity for [those who ate] sacred things. Yohanan ben Gudgada all his life used to eat [unconsecrated food] in accordance with the purity required for sacred things, yet his apron was [considered to possess] midras-impurity for [those who occupied themselves with the water of] purification.
