Talmud su Ecclesiaste 10:6

So we find that Rebbi Simeon disagreed with the Sages and did not act upon his opinion. As we have stated there (Mishnah Ševiït 9:1) “Rebbi Simeon says: all aftergrowth is allowed except the aftergrowth of cabbage because nothing similar grows wild¹³⁰The Mishnah deals with produce of the Seventh year offered for sale by an Am Haäreẓ, a Jew who cannot be trusted with the careful fulfillment of all his religious obligations. The Torah says not only that it is forbidden to plant and sow during the Sabbatical year but also (Lev. 32:5): “Do not harvest the aftergrowth of your harvest,” i. e., it is forbidden to commercially exploit the produce growing on one’s field from the seeds of the preceding year. It is, however, acceptable to collect from one’s fields small amounts for one’s daily needs (and even for storage as long as wild animals can find similar food on the fields.) Rebbi Simeon is of the opinion that a poor person may offer anything for sale since he might (or probably did) collect them from wild growing plants which do not fall under the prohibition. The only exception is produce which is never found growing wild; such vegetables are forbidden for commerce in the production of one’s own field. The Sages, while agreeing that Rebbi Simeon’s position is the one which follows the Biblical precept closely, nevertheless as a Rabbinic ordinance forbid any such buying from untrustworthy people since it is too difficult to enforce the fine distinction made by Rebbi Simeon.
Our example shows that Rebbi Simeon refrained from disagreeing in practice from the rest of the Sages even in purely Rabbinical ordinances. The man cursed by him probably did collect wild aftergrowth, or maybe was known to Rebbi Simeon as a landless person who, therefore, collected from growth on other people’s land that was declared ownerless (הפקר), otherwise his opponent could not have invoked R. Simeon’s own ruling. [This explanation follows Maimonides on the Mishnah. Babli Pesaḥim 51b has a different text, see the discussion in Mishnah Ševiït 9:1, and Kilaim, Halakhah 1:9, and the notes to the Mishnah edition of the Institute for the Complete Israeli Talmud, Ševiït 9:1. The Rome ms. has here “forbidden,” influenced by the Babli.]. But the Sages say that all aftergrowth is forbidden.” Rebbi Simeon bar Yoḥai acted on this in a Sabbatical year. He saw a man harvesting aftergrowth. He said to him: Is that not forbidden, is that not aftergrowth? The man answered him back: Are you not the one who allows it? He retorted: Do not my colleagues disagree with me? He recited over him (Eccl. 10:6): “He who breaches a fence may be bitten by a snake”, and this is what happened to that man.
