Genesis 49:3-7

3Reuben, my firstborn are you, my vigor and firstborn of my power, endowed with extra dignity, endowed with extra strength—

4like water boiling over you will not have extra, for you got up into your father’s bed, when you defiled a maid’s couch.

5Simeon and Levi are brothers, instruments of violence are their knives.

6In their secret counsel may my soul not enter. In their contingent may my honor never be united. For in their anger they slew men, and in their self-will they maimed oxen.

7Cursed be their anger for it was strong and their rage for it was cruel— I will disperse them in Jacob, I will scatter them in Israel.
