Genesis 49:6-7

49:6 O my soul, do not come into their council,

do not be united to their assembly, my heart, ¹ 

for in their anger they have killed men,

and for pleasure they have hamstrung oxen.

49:7 Cursed 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! ² 

[49:6]  ¹ tn The Hebrew text reads “my glory,” but it is preferable to repoint the form and read “my liver.” The liver was sometimes viewed as the seat of the emotions and will (see HALOT 456 s.v. II כָּבֵד) for which the heart is the modern equivalent.

[49:7]  ² sn Divide…scatter. What is predicted here is a division of their tribes. Most commentators see here an anticipation of Levi being in every area but not their own. That may be part of it, but not entirely what the curse intended. These tribes for their ruthless cruelty would be eliminated from the power and prestige of leadership.
