Kapłańska 15:6 Komentarz: Rashi, Siftei Chakhamim & Rav Hirsch

והישב על הכלי AND HE THAT SITTETH ON ANY THING [WHEREON HE SAT THAT HATH AN ISSUE … SHALL BE UNCLEAN] — even though he (the person) is not actually in contact with it: even if there be ten things one upon the other, the lowest being that upon which a זב has once sat, they all communicate uncleanness according to the law applicable to a seat upon which an unclean person has sat, and similarly is the case with an object upon which he has lain (cf. Sifra, Metzora Parashat Zavim, Chapter 3 1).

Even ten vessels one on another. As it is written, “Whoever sits on the vessel that was sat upon by a zov.” This makes a comparison between the sitting of the pure person and the sitting of the zov: Just as the sitting of the zov causes impurity to the vessels even though he does not sit on the vessel, such as the case of the “placed” stone (see later), so too is the sitting of the pure person who acquires impurity from the vessel which contracted impurity from the zov, even if he does not touch it. A “placed” stone is a stone placed on pegs with vessels underneath it, as it is written (Daniel 6:18): “And a stone was brought and placed on the mouth of the pit.” If a menstruant woman or a zov sit on it, even though their weight is not felt on the vessels, the vessels are impure, as it is written (v. 10): “Anything which is beneath him.” Rashi (Shabbos 82b).

V. 6. והישב על הכלי וגו׳. Ganz so wie ein כלי מדרס nicht nur durch unmittelbare Berührung des זב, sondern sofort טמא wird, sobald es sich unter der Körperlast des זב befindet, ebenso teilt es auch in gleicher Weise seine טומאה einem טהור mit, nicht nur, wenn er es berührt, sondern sobald er mit seiner Körperlast, שוכב ,נתלה עומד ,יושב oder נשען, selbst mit vielfacher Zwischenlage, und selbst auf einem אבן מסמא über demselben geruht, selbst ת׳׳כ) עשרה מושבות זה על זה ואפי׳ על גבי אבן מסמא).
