Genesis

                                   Chapter 49

  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.
