Cursed be their fury, because it was stubborn: and their wrath because it was cruel: I will divide them in Jacob, and will scatter them in Israel.

“Read the gospel and you will find it written down; the scribes were from the tribe of Simeon, and the high priests from that of Levi. Since the decision to arrest the Christ and to execute him was taken in their council, the prophet foreknowing that said, "O my soul, come not into their council!" In this passage he talks about the council where they took their decisions by searching for a reason through which they might accuse Christ, so that "they took counsel together in order to arrest Jesus by stealth and kill him." And Isaiah says the same: "Woe to their soul, for they have devised an evil counsel against themselves, saying, 'Let us bind the just one, for he is burdensome to us.' "”

“God forbid, Jacob is saying, that I should share their evil intent or associate myself with their unjust doings. "Because in the heat of their passion they slew people"; their rage turned irrational.… After all, even if Shechem had sinned, there was no need to turn their thirst for blood against everyone. "And in their fury they cut down a bull"; there is reference here to the son of Hamor, calling him a bull because of his hot-blooded maturity. Then, in a reference to their crimes Jacob applies a curse in the words "Cursed be their rage for its ferocity and their frenzy for its willfulness": this touches on the stratagem they employed in deceiving the inhabitants of Shechem and imposed on them by guile. Their rage was "ferocious," he says, headstrong, irrational. "Their frenzy is cursed for its willfulness." When the Shechemites came to believe they had won great favor with them, then it was that Simeon and Levi vented their baleful frenzy and deployed the tactics of a foe against them. Referring to their exploit as sins, he foretells as well the punishment for it that awaits them: "I will disperse them in Jacob and scatter them in Israel." They will be scattered in all directions so that this very thing will be obvious to everyone, namely, that they had persisted in committing this crime out of bravado.”

“As for the historical account, it seems that in this passage [Simeon and Levi] are reproached because, through deceit and fraud, they slaughtered Shechem, the son of Hamor, who after sleeping with their sister had tried to associate himself with the family of Israel. They also destroyed the whole people [of Shechem], so that Israel himself, their father, said to them, "You made me odious in this world." Therefore he curses their cruelty and their recklessness and declares he will scatter them amid the people of Israel, and that from them the Levites and the priests who do not have their own inheritance of land will descend.”

ארור אפם כי עז CURSED BE TIIEIR WRATH, FOR IT IS POWERFUL — Even when he was reproving them he did not curse them but their anger. That is what Balaam said: (Numbers 23:8) “How can I curse them since אל hath not cursed them?” (Genesis Rabbah 99:6) אחלקם ביעקב I WILL DIVIDE THEM IN JACOB — I shall separate them from each other inasmuch as Levi shall not be numbered among the tribes (cf. Numbers 26:62) and thus they (Simeon and Levi) will be divided (cf. Genesis Rabbah 98:5). Another interpretation is: both of these tribes will be dispersed in Israel, and this happened, for you will find that the very poor — the Scribes and elementary teachers — were all of the tribe of Simeon, and this was so in order that this tribe should be dispersed, since such poor people must wander from city to city to eke out a livelihood. As for the tribe of Levi, He made them travel round from one threshing floor to another to collect their heave offerings and tithes; thus He caused them also to be “scattered” but in a more respectable manner (Genesis Rabbah 99:6).”

“Cursed be their anger, for it was fierce,.... It was sinful anger in the nature of it, and so criminal and detestable; it was strong, fierce, and furious in its operation and effects, and so justly cursed; not their persons, but their passions: and their wrath, for it was cruel; it issued in the cruel and barbarous slaughter of the inhabitants of Shechem; the same thing as before in other words repeated, to express his great abhorrence of their wrath and rage. Aben Ezra thinks that the words may be considered either as a prophecy or a prayer, that their anger might cease: what follows is certainly a prophecy: I will divide them in Jacob, and scatter them in Israel; which he is said to do, because he foretold it would be done; as Jeremiah is said to root out and pull down kingdoms, because he prophesied thereof, Jer 1:10 and this was fulfilled in the tribes of Simeon and Levi; as for the tribe of Simeon, that had not a distinct part by itself in the land of Canaan, but had their inheritance out of the portion, and within the inheritance of the tribe of Judah, Jos 19:1 and their cities did not join to one another, as Aben Ezra observes, but lay scattered up and down in the tribe of Judah; and when they were increased and straitened for room, many of them went without the land, to the entrance of Gedor, where they of Ham, or the Egyptians, had dwelt, and others to Mount Seir in Edom, Ch1 4:39 and it is a notion which prevails with the Jews, and which Jarchi takes notice of, that a great many of this tribe were scribes and teachers of the law, and even teachers of children, and by which they lived among the several tribes; and so the Jerusalem Targum,"I will divide the tribe of Simeon, that they may be scribes and teachers of the law in the congregation of Jacob.''And as for the tribe of Levi, it is well known that they had no inheritance in the land of Canaan, but had forty eight cities assigned them in the several tribes here and there; and thus Jacob's prophecy had an exact accomplishment.”

“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, Ch1 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. 9. A lion's whelp is Judah: From the prey, my son, thou hast ascended, He couched, lying down like a strong lion And like a lioness; who shall arouse him? 10. From Judah the scepter shall not depart, Nor a teacher from his offspring, Until that Shiloh shall come, And to him shall be assembled the peoples. 11. Binding his colt to the vine, And to the choice vine the foals of his ass, He washed his garments in wine, His clothes in the blood of the grape. 12. With wine shall his eyes be red, And his teeth shall be white with milk.”

“Scatter them. Levi had no division allotted to him, but only some cities among the other tribes; and Simeon had only a part of Juda’s lot, which was so small, that his descendants were forced to seek for a fresh establishment; some in Gader, others in Mount Seir. (1 Paralipomenon iv. 39; Josue xi. 2.) Simeon alone was not blessed by Moses, Deuteronomy xxxiii. (Du Hamel) — The Levites obtained a blessing, on account of their distinguished zeal; (Numbers xxv.) while Zambri rivets, as it were, the curse upon the family of Simeon. (Menochius)”
