Let not my soul go into their counsel, nor my glory be in their assembly: because in their fury they slew a man, and in their selfwill they undermined a wall.

“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.”

בסדם אל תבא נפשי O MY SOUL, COME NOT THOU INTO THEIR SECRET DELIBERATION (סוד may have the sense of plot) — this has reference to the story of Zimri, (Numbers 25:6-15) when the tribe of Simeon assembled and brought the Midianitish woman before Moses, saying, “Is this woman forbidden or permitted to be taken as a wife? If you say she is forbidden, who made the daughter of Jethro permissible to you in marriage” (See Sanhedrin 82b) — let not my name be mentioned in connection with that event! Indeed, it is said (Numbers 25:14) “Zimri, the son of Zalu, a prince of a father’s house among the Simeonites” — but Scripture does not state “a son of Jacob”. בקהלם UNTO THEIR ASSEMBLY — when Korah of the tribe of Levi will assemble the entire congregation against Moses and Aaron — אל תחד כבודי MY GLORY BE NOT THOU UNITED — let my name not be associated there with them! (Genesis Rabbah 98:5) And so it was, for it is said (Numbers 16:1) “Korah, the son of Izhar, the son of Kohath. the son of Levi” — but it does not say “the son of Jacob”. In Chronicles, however, (1 Chronicles 6:22,23), where the genealogy of Korah is traced in connection with the “Duchan” (properly, the platform — the place on which the Levites were stationed for the service of song in the Temple) it is said, “the son of Korah, the son of Izhar, the son of Kohath, the son of Levi, the son of Israel (Genesis Rabbah 98:5). אל תחד כבדי MY GLORY BE NOT THOU UNITED — כבוד is masculine and therefore you must needs explain the phrase as though he were addressing himself to “the glory” saying, “thou, my glory, be not united with them!” תחד is exactly the same grammatical form (2nd masc. sing. and not 3rd fem. sing.) as (Isaiah 14:20) “Thou shall not be united (אל תחד) with them in burial” כי באפם הרגו איש FOR IN THEIR WRATH THEY SLEW A MAN — This refers to Hamor and the people of Shechem, and they are spoken of as איש “one” man because they were all regarded as of no more account than one man when it was a matter of attacking them. It likewise states in the history of Gideon, (Judges 6:16) “And thou shalt smite the Midianites as one man”, and similarly concerning Egypt, (Exodus 15:1) “The horse (singular) and its rider (singular) hath he thrown into the sea” (i.e. the whole army as though it consisted of but one horse and its rider). This is a Midrashic interpretation (Genesis Rabbah 99:6). The plain meaning of the use of the singular form is: a group of men is called “a man” having in mind each one separately, so that the meaning is: they slew every man with whom they were angry. Similar is (Ezekiel 19:3) “and he learned to catch the prey, he devoured (אדם) a man” (which is the same as בני אדם “men”) וברצונם עקרו שור AND IN THEIR SELFWILL THEY LAMED AN OX — they desired to exterminate Joseph who is called שור, as it is said, (Deuteronomy 33:17) “His firstling bullock (שורו) (Joseph), majesty is his”. עקרו means in old French essarter. It has the same meaning as in (Joshua 11:6) “Thou shalt hamstring (תעקר) their horses”.”

Ramban Jewish

“FOR IN THEIR ANGER THEY SLEW A MAN AND IN THEIR SELF-WILL THEY DISABLED AN OX (‘SHOR’). The meaning of this is that they committed violence in their wrath in that they were angry at Shechem, and it was to satisfy their own desire and not because of the guilt or sins of the slain. Now Onkelos says that the word shor (ox) should be understood as shur (wall) with a shuruk,. Thus the word should be understood as shur (wall) rather than shor (ox). The Torah-script has no vowel signs, and for the sake of interpretation, a difficult word may sometimes be interpreted as if it were vowelled differently than the traditional reading. as in the verse, Daughters treaded on the wall (‘shur’). Thus Onkelos translated the word shor in the present verse as “the wall of the enemy,” similar in expression to the verse: Mine eye also hath gazed on them that lie in wait for me (‘b’shuroi’). The meaning of the verse is thus: “and they uprooted a city surrounded with a wall, slaying their children and women after having killed the men of the city.” The word ikru (disabled) would then be similar in use to the verse, Ekron shall be rooted up (‘tei’akeir’). Others have explained that the ox, which is the largest of cattle, is an allusion to Hamor and his son Shechem, the prince of the country, just as in the verses: His firstling bull, majesty is his; Ye kine of Bashan, that are in the mountain of Samaria. Similarly do the verses surname the great princes “rams” is generally translated, “the mighty men of Moab,” but literally it means “the rams of Moab.” and “he-goats.” is generally translated, “the chief ones of the earth,” but literally it means “the he-goats of the earth.” The correct interpretation appears to me to be that the verse is to be understood in its usual sense as stating that in their anger they killed each man of whom they were wrathful; and in their self-will, after their anger had been calmed by the slaying of the men, they uprooted all oxen, this being an allusion to their cattle and their possessions, including everything that was in the home and everything in the field. Now Jacob mentioned this in order to state that he had no part in all these secret deliberations of theirs, even in the removal of the cattle and possessions, or any aspect of the spoiling and plundering of the people of the city of Shechem. The word ikru [in the expression, ikru shor], has the same meaning as in the verse: Thou shalt hemstring (‘te’akeir’) their horses. But the expression and purport is all one.”

“O my soul, come not thou into their secret,.... Their cabinet counsels, combinations and conspiracies; this Jacob said, as abhorring the wicked counsel they had took of slaying the Shechemites; and lest any should think he was concerned in it, or connived at it, he expressed a detestation of the fact on his dying bed: the future tense may be put for the past; and so Onkelos renders it, "my soul was not in their secret"; and so the other two Targums paraphrase it, that when they got and consulted together, his soul was not pleased and delighted with their counsel, but abhorred it; or "my soul shall not come", which Jarchi thinks prophetical refers to the case of Zimri, the son of Salu, of the tribe of Simeon, as the following clause to the affair of Korah, of the tribe of Levi, as foreseeing and disapproving them, and desiring they might not be called by his name, or his name called upon them, Num 25:14. unto their assembly, mine honour, be not thou united; the same thing expressed in different words; by his "honour or glory" he means his soul, the more honourable part of man, or his tongue, with which man glorifies God; and hereby Jacob intimates, that he did not in thought, and much less in express words, give any consent unto, and approbation of the deed of those two sons of his, and that he never was, nor never desired to be with them in their meetings and consultations: for in their anger they slew a man; Hamor or Shechem, together with all the males of the city; and so "man" may be put for "men", the singular for the plural, as is frequent. The Targum of Jonathan is, a king and his governor; and the Targum of Jerusalem, kings with governors: and in their selfwill they digged down a wall; not the wall of the city of Shechem, which does not appear to be walled, by their easy access into it; and if it was, they do not seem to have had proper instruments for such an undertaking, nor a sufficient number for such work, and which would have required longer time than they used, unless it was a poor wall indeed: rather the wall of Shechem's house, or the court before it, which they dug down, or broke through to get in and slay Hamor and Shechem, and take away their sister; though the word, as here pointed, always signifies an ox; and so the Samaritan and Septuagint versions render it, they hamstringed a bull, or houghed an ox, just in like manner as horses are said to be houghed, Jos 11:6 and which some understand (l) figuratively of a prince or ruler; so great personages are called bulls of Bashan, Psa 22:12 and interpret it either of Hamor or of Shechem, who was a prince among his people, and furious in his lust towards Dinah, and so this clause is much the same with the former: and besides, him they enervated by circumcision, and took the advantage of this his condition at the worst, and slew him, which seems to be the true sense of the text, agreeably to Gen 34:25 but the Jerusalem Targum paraphrases it of Joseph, whom his brethren sold, who was like unto an ox; and so Jarchi interprets it of him, whom they designed to slay, see Deu 33:17 but it is better to take the words in a literal sense, either of the oxen that Simeon and Levi took from the Shechemites, which they plucked or drove away from their mangers, as some render the words (m); and some of them they might hough or hamstring, that they might not get away from them, see Gen 34:28 or rather of Shechem himself, who was "a prince", a word which has some likeness and affinity to this in the text.

“Into their secret council, etc. - Jacob here exculpates himself from all participation in the guilt of Simeon and Levi in the murder of the Shechemites. He most solemnly declares that he knew nothing of the confederacy by which it was executed, nor of the secret council in which it was plotted. If it should be said that the words תבא tabo and תחד techad should be translated in the future tense or in the imperative, as in our translation, I shall not contend; though it is well known that the preterite is often used for the future in Hebrew, and vice versa. Taken thus, the words mark the strong detestation which this holy man's soul felt for the villany of his sons: "My soul shall not come into their secret council. My honor shall not be united to their confederacy. For in their anger they slew a man - איש ish, a noble, an honorable man, viz., Shechem. And in their pleasure - This marks the highest degree of wickedness and settled malice, they were delighted with their deed. A similar spirit Saul of Tarsus possessed previously to his conversion; speaking of the martyrdom of St. Stephen, St. Luke says, Act 8:1 : Σαυλος δε ην συνευδοκων τῃ αναιρεσει αυτου· And Saul was gladly consenting to his death. He was with the others highly delighted with it; and thus the prediction of our Lord was fulfilled, Joh 16:2 : Yea, the time cometh, that whosoever killeth you will think that he doeth God service. And it is represented as the highest pitch of profligacy and wickedness, not only to sin, but to delight in it; see Rom 1:32. As the original word רצון ratson signifies, in general, pleasure, benevolence, delight, etc., it should neither be translated self-will nor willfulness, as some have done, but simply as above; and the reasons appear sufficiently obvious. They murdered a prince - Hamor, the father of Shechem. Instead of שור shor, which we have translated a wall, and others an ox, I read שר sar, a prince, which makes a consistent sense; (see Kennicott's first Dissertation, p. 56, etc.); as there is no evidence whatever that Simeon and Levi either dug down a wall or houghed the oxen, as some have translated the passage; Or houghed oxen; on the contrary, the text, Gen 34:28, Gen 34:29, proves that they had taken for their own use the sheep, oxen, asses, all their wealth, their wives, and their little ones.”

“Slew a man, viz., Sichem, the son of Hemor, with all his people, chap. xxxiv. Mystically and prophetically it alludes to Christ; whom their posterity, viz., the priests and the scribes, put to death. (Challoner) — A wall, Sichem, which they destroyed: or, according to the Septuagint, “they ham-strung” a bull, as the same Hebrew word signifies; both which may refer to the prince of the town, or to Joseph, (Calmet) in whose persecution these two were principally concerned. Jacob declares, he had no share in their attack upon the people of Sichem: his soul, or his glory, was not impaired by their misconduct. (Haydock)”
