Musar sur Les Proverbes 25:6

We find that Korach quarrelled with the Priests and the Levites. He was jealous of Elitzafan son of Uzziel having been appointed to the position of prince of the Levites, and of Aaron having been appointed High Priest. The two hundred and fifty men who supported him all violated the principle of trying to usurp the superior positions occupied by others, as we have already explained. This is similar to the Rabbis saying that במופלא ממך אל תדרוש, במכוסה ממך אל תחקור (Chagigah 13), "that which is too difficult for you, do not investigate, and that which is concealed from you do not seek it out."

In one's sitting: that one's place be among the lowly and not among the prominent. This is likewise stated explicitly in scripture: "Do not glorify yourself before a king, and do not stand in the place of great men; for it is better that he say to you, 'Come up here', than to humble you before a prince..." (Mishlei 25:6-7). Likewise our sages of blessed memory said: "distance two or three places from your [proper] place and sit until you are told 'come forward!', rather than to go up until they tell you 'move back!'" (Vayikra Raba 1:5).
