Simeon and Levi are brethren; instruments of cruelty are in their habitations. 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. 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.
Because Simeon and Levi had cruelly killed the men of Shechem, they would be dispersed and scattered in Israel. By the time of the second census in Numbers 26, they were the two smallest tribes. Jacob cursed their cruel deception but not the people of these two tribes themselves.
