Genesis 49:5-7

5Simeon and Levi are brethren; instruments of cruelty are in their habitations.1 6O my soul, come not thou into their secret; unto their assembly, mine honour, be not thou united: for in their anger they slew a man, and in their selfwill they digged down a wall.2 7Cursed be their anger, for it was fierce; and their wrath, for it was cruel: I will divide them in Jacob, and scatter them in Israel.
