The garments of an am haaretz have midras [-contamination] for perushim. Garments of perushim have midras[-contamination] for those who eat terumah. Garments of those who eat terumah have midras[-contamination] for [those who eat] kodesh. Garments of [those who eat] kodesh have midras[-contamination] for [those who handle] purification water.  Yosef ben Yoezer was the most devout of the Kohanim; yet his napkin was [deemed to have] midras[-contamination] for [those who eat] kodesh.  Yochanan ben Gudgada used to eat according to the purity [regulations] of kodesh all his life; yet his napkin was [deemed to have] midras[-contamination] for [those who handle] purification water.

The stringency of kodesh compared to terumah is [as follows]:  (a) We may immerse vessels within [other] vessels for terumah, but not for kodesh.  (b) The bottom, the inside, and the handle [are considered separate vessels] as regards terumah, but not as regards kodesh.  (c) Someone carrying a midras may [simultaneously] carry terumah, but not kodesh.  (d) The garments of those who eat terumah have midras[-contamination] for [those who eat] kodesh.  (e) Unlike the rule of kodesh is the rule of terumah; for in the case of [immersing garments to be worn while handling] kodesh, one must untie [the knots], dry, immerse, and then retie [them]; but in [the case of] terumah, one may tie and then immerse.

(f) Vessels that were completed in a state of taharah require immersion for [use with] kodesh, but not for [use with] terumah.  (g) A vessel combines whatever is in it with regard to kodesh, but not with regard to terumah.  (h) The fourth degree [of contamination] in the case of kodesh is invalid, but [only] a third degree [is invalid] in the case of terumah.  (i) In the case of terumah, if one of a person's hands became contaminated, the other one is [still] pure; but in the case of kodesh, he must immerse them both, for one hand contaminates the other as regards kodesh, but not as regards terumah.

(j) We may eat dry food with contaminated hands if [the foods are] terumah, but not if they are kodesh.  (k) The onein and one who needs to bring an atonement-offering require immersion for [eating] kodesh, but not for [eating] terumah.
