These were next in age to Reuben, and they also had been a grief and shame to Jacob, when they treacherously and barbarously destroyed the Shechemites, which he here remembers against them. Children should be afraid of incurring their parents’ just displeasure, lest they fare the worse for it long afterwards, and, when they would inherit the blessing, be rejected. Observe, 1. The character of Simeon and Levi: they were brethren in disposition; but, unlike their father, they were passionate and revengeful, fierce and uncontrollable; their swords, which should have been only weapons of defence, were (as the margin reads it, Gen. 49:5) weapons of violence, to do wrong to others, not to save themselves from wrong. Note, It is no new thing for the temper of children to differ very much from that of their parents. We need not think this strange: it was so in Jacob’s family. It is not in the power of parents, no, not by education, to form the dispositions of their children; Jacob bred his sons to every thing that was mild and quiet, and yet they proved to be thus furious. 2. A proof of this is the murder of the Shechemites, which Jacob deeply resented at the time (Gen. 34:30) and still continued to resent. They slew a man, Shechem himself, and many others; and, to effect that, they digged down a wall, broke the houses, to plunder them, and murder the inhabitants. Note, The best governors cannot always restrain those under their charge from committing the worst villanies. And when two in a family are mischievous they commonly make one another so much the worse, and it were wisdom to part them. Simeon and Levi, it is probable, were most active in the wrong done to Joseph, to which some think Jacob has here some reference; for in their anger they would have slain that man. Observe what a mischievous thing self-will is in young people: Simeon and Levi would not be advised by their aged and experienced father; no, they would be governed by their own passion rather than by his prudence. Young people would better consult their own interests if they would less indulge their own will. 3. Jacob’s protestation against this barbarous act of theirs: O my soul, come not thou into their secret. Hereby he professes not only his abhorrence of such practices in general, but his innocence particularly in that matter. Perhaps he had been suspected as, under-hand, aiding and abetting; he therefore thus solemnly expresses his detestation of the fact, that he might not die under that suspicion. Note, Our soul is our honour; by its powers and faculties we are distinguished from, and dignified above, the beasts that perish. Note, further, We ought, from our hearts, to detest and abhor all society and confederacy with bloody and mischievous men. We must not be ambitious of coming into their secret, or knowing the depths of Satan. 4. His abhorrence of those brutish lusts that led them to this wickedness: Cursed be their anger. He does not curse their persons, but their lusts. Note, (1.) Anger is the cause and original of a great deal of sin, and exposes us to the curse of God, and his judgment, Matt. 5:22. (2.) We ought always, in the expressions of our zeal, carefully to distinguish between the sinner and the sin, so as not to love nor bless the sin for the sake of the person, nor to hate nor curse the person for the sake of the sin. 5. A token of displeasure which he foretels their posterity should lie under for this: 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 the 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. 25:14), had it bound on. Note, Shameful dispersions are the just punishment of sinful unions and confederacies.
