Musar sobre I Crônicas 23:13

Another difficulty is the verse בוקר ויודע ה' את אשר לו, "In the morning G–d will announce who is His, etc," and Rashi's comment in the name of Bamidbar Rabbah that the morning is a suitable time. The evening, a time when we have drunk wine, is not a suitable time to appear in front of G–d. Moses intended to delay matters in the hope that they would change their minds, and desist. One has to understand what this so called עת שכרות, “a time for drunkenness" is all about. The Midrash there also has Moses arguing that Korach committed an effrontery by changing what was as established a pattern by G–d as the division between evening and morning, light and dark, etc. It compared the selection of Aaron as High Priest as something similar to a law of nature! The Midrash bases that on a verse in Chronicles I 23,13: "ויבדל אהרון להקדישו בקדש הקדשים, "Aaron was set apart to sanctify him to be in the inner sanctum," where G–d uses the same expression for the distinction of Aaron as He had used when separating day and night. How could Rashi or the Midrash respectively, make such a comparison? Was Aaron's selection comparable to an Act of Creation?
