Genesis 49:5-7 KJV

5 Simeon and Levi are brethren; instruments of cruelty are in their habitations.

6 O 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.

7 Cursed 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.
