Талмуд к Пара 11:8
אֵזוֹב שֶׁהִזָּה בוֹ, כָּשֵׁר לְטַהֵר בּוֹ אֶת הַמְּצֹרָע. לִקְּטוֹ לְעֵצִים וְנָפְלוּ עָלָיו מַשְׁקִין, מְנַגְּבוֹ וְהוּא כָשֵׁר. לִקְּטוֹ לְאֳכָלִין וְנָפְלוּ עָלָיו מַשְׁקִין, אַף עַל פִּי שֶׁנִּגְּבוֹ, פָּסוּל. לִקְּטוֹ לְחַטָּאת, כִּמְלֻקָּט לְאֳכָלִין, דִּבְרֵי רַבִּי מֵאִיר. רַבִּי יְהוּדָה וְרַבִּי יוֹסֵי וְרַבִּי שִׁמְעוֹן אוֹמְרִים, כִּמְלֻקָּט לְעֵצִים:
Иссоп, которым посыпали [во время ритуала чата ], действителен для использования при очищении метзоры [человека с кожным заболеванием, которое делает его нечистым, и чей ритуал очищения включает иссопа). Если кто-то выбрал его [иссопа] как дерево, и на него упали жидкости, его можно высушить, и это действительно [для обсыпки]. Если кто-то выбрал его как еду и жидкость упала на него, даже если он высушил его, он недопустим [для окропления]. По словам раввина Меира, если кто-то выбрал его для использования в ритуале чата , то это как если бы его выбрали как еду. Раввин Иегуда, раввин Йосе и раввин Шимон говорят: [это] как если бы оно было выбрано как дерево.
Jerusalem Talmud Sotah
The prohibition of prior use is spelled out in the Torah for the red cow only (Num. 19:2). By rabbinic tradition, the prohibition is extended to the water used for purifying as explained at length in Mishnah Parah. R. Eliezer extends the prohibition to anything used in any ritual of purification by hyssop and water., as it was stated76This baraita is not quoted in any other source; the Tosephta quoted in the preceding Note shows that the source of the baraita is the school of R. Eliezer.: If he sprinkled with it for purifying, it is disqualified for the sufferer from skin disease. If he sprinkled with it for the sufferer from skin disease, it is disqualified for purifying. 77The argument presented here is intended to show an error in the position of R. Eliezer. The argument of R. Yose (ben Ḥalaphta) is not found in any other source.
The argument goes as follows: Everybody agrees that the rules of purification from skin disease are not as stringent as those from the impurity of the dead. If using hyssop for purifying from the impurity of the dead would disqualify it as instrument for purifying from skin disease, one must require that one hyssop cannot be used for several people defiled by contact with a corpse. But is was general practice that the Temple provided a purification service where a person was standing in a window and was sprinkling continuously on the people walking by below, always using the same hyssop (Mishnah Parah11:4); no dissent by R. Eliezer is recorded. Therefore, practice must follow the Mishnah, not R. Eliezer. Rebbi Yose said, would that not be an argument de minore ad majus? Since for the sufferer from skin disease, for whose ceremony use does not disable, if he sprinkled with it for purifying, it is disqualified for the sufferer from skin disease; purifying, for whose ceremony use does disable, if he sprinkled with it for purifying, is it not logical that it should be disqualified for purifying?
