Cursed was their anger - The first motions of their violence were savage; and their excessive or overflowing wrath, עברה ebrah, for it was inflexible - neither the supplications of the males, nor the entreaties, tears, cries, and shrieks of the helpless females, could deter them from their murderous purpose; for this, Gen 49:5, they are said to have accomplished.
I will divide them out, אחלקם achallekem, I will make them into lots, giving a portion of them to one tribe, and a portion to another; but they shall never attain to any political consequence. This appears to have been literally fulfilled. Levi had no inheritance except forty-eight cities, scattered through different parts of the land of Canaan: and as to the tribe of Simeon, it is generally believed among the Jews that they became schoolmasters to the other tribes; and when they entered Canaan they had only a small portion, a few towns and villages in the worst part of Judah’s lot, Jos 19:1, which afterwards finding too little, they formed different colonies in districts which they conquered from the Idumeans and Amalekites, 1Ch 4:39, etc. Thus these two tribes were not only separated from each other, but even divided from themselves, according to this prediction of Jacob.
8. Judah! thou! Thy brethren shall praise thee.
Thy hand, in the neck of thine enemies:
The sons of thy father shall bow themselves to thee.
