Genesis 49:3-7

3Reuben, you are my firstborn, my might and the beginning of my strength, outstanding in dignity, outstanding in power.

4You are destructive like water and will not excel, for you got on your father’s bed, then you defiled it – he got on my couch!

5Simeon and Levi are brothers, weapons of violence are their knives!

6O my soul, do not come into their council, do not be united to their assembly, my heart, for in their anger they have killed men, and for pleasure they have hamstrung oxen.

7Cursed be their anger, for it was fierce, and their fury, for it was cruel. I will divide them in Jacob, and scatter them in Israel!
