Cursed be their anger, for it was fierce; and their wrath, for it was cruel: I will {f} divide them in Jacob, and scatter them in Israel.

(f) For Levi had no part, and Simeon was under Judah, Jos 19:1 till God gave them the place of the Amalekites, 1Ch 4:43.

Wesley's Notes

49:7 Cursed be their anger - Not their persons. We ought always in the expressions of our zeal carefully to distinguish between the sinner and the sin, so as not to love or bless the sin for the sake of the person, nor to hate or curse the person for the sake of the sin. I will divide them - The Levites were scattered throughout all the tribes, and Simeon's lot lay not together, and was so strait that many of that tribe were forced to disperse themselves in quest of settlements and subsistence. This curse was afterwards turned into a blessing to the Levites; but the Simeonites, for Zimri's sin, Num 25:6 - 14, had it bound on.

Matthew Henry's Concise Commentary

49:3-7 Reuben was the first-born; but by gross sin, he forfeited the birthright. The character of Reuben is, that he was unstable as water. Men do not thrive, because they do not fix. Reuben's sin left a lasting infamy upon his family. Let us never do evil, then we need not fear being told of it. Simeon and Levi were passionate and revengeful. The murder of the Shechemites is a proof of this. Jacob protested against that barbarous act. Our soul is our honour; by its powers we are distinguished from, and raised above, the beasts that perish. We ought, from our hearts, to abhor all bloody and mischievous men. Cursed be their anger. Jacob does not curse their persons, but their lusts. I will divide them. The sentence as it respects Levi was turned into a blessing. This tribe performed an acceptable service in their zeal against the worshippers of the golden calf, Ex 32. Being set apart to God as priests, they were in that character scattered through the nation of Israel.
