Or HaChaim on Genesis 49:6/אור החיים על בראשית מ״ט:ו׳

1 בסודם אל תבא נפשי, "My soul, do not come to their counsel." We need to understand what precisely Jacob had in mind. Our sages in Sanhedrin 109 say that Jacob referred to the affair with Zimri in which the tribe of Shimon disgraced itself, and to the uprising of Korach which was a taint on the tribe of Levi. They also state that the words באפם הרגו איש "in their anger they slew a man," refer to Chamor and the men of Shechem, whereas the words וברצונם עקרו שור, "and it was their wish to uproot an ox," refer to their violence against Joseph (compare Targum Yerushalmi). These comments are all homiletical. One of the difficulties with this explanation is why Jacob would list events that were far in the future ahead of events which had already taken place, such as the violence against Joseph and Chamor? How could the word כי be used in this verse when it does not relate to anything which preceded it? Besides, why would Jacob also associate Levi with the affair in which Zimri would disgrace himself by sleeping with a Midianite princess? Why did Jacob choose the expression ברצונם, "when it pleased them," to describe Shimon and Levi's planned violence against Joseph?

2The plain meaning of the verse is that the entire verse speaks about the incident with Joseph. When Jacob refers to בסודם, "their secret," he meant that he did not want to be associated with these two brothers from the moment they began to hate Joseph, although they concealed their hatred for a while. When Jacob spoke about אל תבא נפשי, this was his way of disassociating himself from any guilt concerning the behaviour of Shimon and Levi. Just as he had not transmitted spiritually corrupt genes to Reuben, so he had not burdened Shimon and Levi with spiritually defective genes when he fathered either one of them. Any evil concocted by these two brothers did not originate with him.

3Jacob also wanted to state that he would not be punished for anything these two brothers had done because of his preferential treatment of Joseph being an underlying cause of the brothers' jealousy and hatred of him.

4When Jacob added: ובקהלם אל תחד כבודי, "my honour do not join their congregation," he referred to the moment when Shimon and Levi hatched the plot to kill Joseph (37,20). He did not want these two sons to be known as "the sons of Jacob" as of that moment. Jacob considered such a designation of these two as an affront to his honour. Tanchuma in Parshat Vayeshev understands the word כבוד as a reference to the presence of the שכינה which had departed from Jacob the moment Joseph had become lost. The word כי in בי באפם הרגו איש, is the justification for Jacob not wanting his name associated with these two brothers. He referred to their having killed a man although we know in retrospect that this did not happen. Jacob considered the brothers' willingness to kill Joseph and to throw him into a pit full of reptiles as equivalent to exposing Joseph to many kinds of deaths.

5וברצונם עקרו שור, "and they uprooted an ox at their pleasure." Jacob added that even after their anger had already evaporated, after they had thrown Joseph into the pit and Yehudah spoke words of appeasement to them, they continued to act evilly. The Talmud Sotah 36 states that Joseph should have been the progenitor of 12 tribes. His encounter with the wife of Potiphar whose temptations he withstood only with the greatest amount of willpower caused him to forfeit the privilege of founding the other ten tribes. Had it not been for Shimon and Levi who had wanted to uproot Joseph's future, none of this would have happened.
