Genesis 49:3-7

3“Reuben, you are my firstborn, My might and the beginning of my strength, The excellency of dignity and the excellency of power.

4Unstable as water, you shall not excel, Because you went up to your father’s bed; Then you defiled it— He went up to my couch.

5“Simeon and Levi are brothers; Instruments of cruelty are in their dwelling place.

6Let not my soul enter their council; Let not my honor be united to their assembly; For in their anger they slew a man, And in their self-will they hamstrung an ox.

7Cursed be their anger, for it is fierce; And their wrath, for it is cruel! I will divide them in Jacob And scatter them in Israel.
