Chasidut su Ecclesiaste 5:5

None of the prophets were satisfied with spreading their greatness to individuals alone. Rather, they tried to raise their entire generation to the messianic telos and the tikkun of the end times, as it says in the midrash above that is was not just individuals but rather all of them [who were prophets]. It says in the Zohar (Acharei Mot 79) about the generation of R. Simon b. Yokhai “Rabbi Yehudah taught, “The generation in which Rabbi Shimon b. Yokhai dwells are all virtuous, all devout, and sin-fearing, and Shekhinah dwells among them, which is not so in other generations...For when R. Shimon uttered the mystery of this verse, the eyes of all the Companions streamed tears , and all the words that he spoke were clear in their eyes...It has been taught: In the days of R. Shimon, a person would say to his fellow, ‘Open your mouth and let your words shine!’ After R. Shimon passed away, they would say, ‘Do not let your mouth make your flesh sin.’²¹⁶Ecclesiastes 5:5. If even the donkey of Rabbi Pinhas ben Yair was illuminated, observed the Torah, was stringent beyond the letter of the law, and apprehended through inspiration that its food was not tithed,²¹⁷See Talmud Hullin 7a-b. we can only imagine the extent of the prophet’s desire to make of Israel “a kingdom of priests and a holy nation.”²¹⁸Exodus 19:6.

The Zohar makes several mentions of statements that lack a foundation or accepted tradition from one’s Rav. (Yithro, 87a): Rabbi Yitzchak opened (Kohelet, 5:5), “Do not let your mouth cause your flesh to sin.” How greatly does man need to be careful not to err in the words of Torah, and not to derive explanations of the Torah that he did not receive from his Rav. He who says a word of Torah that he did not know or receive from his Rav, of him it is written, “Do not make an idol or any image.” The Holy One, blessed be He, will exact punishment from him in the world-to-come. At the time when his soul wants to ascend to its place, it will be pushed outside, and will be destroyed from the binds of eternal life of all other souls. The Zohar then compares illegitimate innovations to fathering a bastard. As it is taught (in the continuation of Kohelet 5:5), “Why should God be angry at your voice.” “Voice,” is man’s soul. Rabbi Chiyya said, therefore it is written, “Hashem your God is a jealous God.” For what reason? It is because He is jealous for His name’s sake in everything. If it is because of the form of the face, (of the bastard) He is jealous for His name, since it is lying in His name. And the same is true for the Torah, (when one teaches that which he does not know and did not receive from his Rav.)”
