“Those who cause man to sin by a word They are the false prophets. and him who reproves in the gate they trap (יְקשׁוּן. Jonathan renders:) And for the one who reproves them, they seek for him a stumblingblock. (יְקשׁוּן is) an expression related to מוֹקֵשׁ, a trap. and they mislead the righteous through fraud And they pervert with fraud the cause of the just [from Jonathan].”

“Woe, Ariel. In this part he sets forth a threat against the people, or against the city; and it is divided into two parts. In the first he threatens the punishment of temporal destruction; in the second, the punishment of spiritual blindness, Be astonished. Concerning the first, two things. In the first he threatens destruction; in the second he sets forth some sort of consolation, and it shall be as a dream. The first into two. In the first, the destruction of Jerusalem by the Babylonians. In the second, by the Romans, and I will encompass. Concerning the first, three things. First he recalls its former dignity. Ariel, that is, lion of God, because by the power of God, in the times of David and Solomon, it feared no one, just as a lion does not either. Proverbs 30: a lion, strongest of beasts, will tremble at the meeting of no one. Or on account of the altar of holocausts, which was there, which consumed animals as a lion does. And so as it is taken in Ezekiel 43: or perhaps on account of its shape, because it was situated after the manner of a lion. He conquered. 1 Kings 17: for I conquered the lion and the bear. Second he sets forth the destruction, positing three things: the cessation of feasts, add, as if to say, for many years. Have rolled around, that is, have perished. Hosea 3: they shall sit many days without sacrifice and without ephod. Siege, and I will encircle with a rampart, namely by the Chaldeans. Ezekiel 4: it shall be in a state of siege; and he hints at the conquest arising from sorrow, and she shall be sorrowful. Lamentations 1: many are her groans, etc. Third he sets forth the restoration made under Jesus the high priest and others, concerning whom the whole of Esdras treats. And it shall be to me; as if to say: retaining only a shadow of its former dignity. But on the contrary: Haggai 2: great is the glory of this latter house, more than of the former. And it must be said that this is said on account of the fact that it was visited by the Son of God himself, even bodily. And I will encompass. Here he threatens destruction by the Romans; and concerning this he sets forth four things. First, the siege, and I will encompass as a sphere, that is, round about. Luke 19: your enemies shall encompass you with a rampart. Habakkuk 1: he shall laugh at every fortification, and shall heap up a mound. Second, the humiliation of the besieged, you shall be humbled; and the sign of the humiliation: you shall speak out of the earth, that is, just as if you were under the earth, you shall even be heard speaking lowly, bearing the words of a python-spirit, who used to chant incantations silently. Zephaniah 3: I will take away out of your midst the evil-speakers of your pride. Or the merit of the humiliation, reproving in them the sin of avarice, you shall speak out of the earth; and of idolatry, and it shall be as of a python-spirit. Third he sets forth the multitude of enemies, and it shall be as dust: Joel 1: a nation has come up; or the destruction of the enemies, as above, 17: it shall be carried off like the dust of the mountains before the face of the wind. Fourth he sets forth the destruction itself, and it shall be suddenly: metaphorically, on account of the ferocity of the enemies. Jeremiah 4: he shall come up as a cloud, and as a tempest: his chariots are swifter than eagles. And it shall be as a dream. Here he applies a certain consolation drawn from the punishment of the enemies, because, like a vain thing, they shall come to nothing, carrying back no advantage from the destruction of Judea, just as neither does one who is hungry or thirsty gain anything from food or drink dreamed of. Ecclesiasticus 34: vain hope and a lie are to a senseless man, and dreams lift up the imprudent. Zechariah 12: I will make Jerusalem a stone of burden to all peoples. Note on that word, and it shall be as a dream, that a thing is called a dream, first, on account of vanity. Ecclesiasticus 34: the vision of dreams is according to this; second, on account of brevity. Job 20: like a dream flying up he shall not be found. Third, on account of the obscurity of its knowing. Job 33: through a dream, in a vision of the night. Fourth, on account of the perversity of the soul. Below, 56: sleeping, and loving dreams. Be astonished, here he threatens the punishment of blindness: and first he foretells the blindness of the Jews; second, the conversion of the Gentiles, is it not yet. Concerning the first, two things. First he sets forth the blindness; second he assigns its reason, and the Lord said. Concerning the first, three things. First he foretells the blindness, setting forth those things which disturb the judgment of reason: be astonished, from the consideration of the evils of fault or of punishment. Jeremiah 2: be astonished, O heavens, at this, and, O gates of heaven, be very desolate. And wonder, from the consideration of great things. Psalm 138: wonderful are your works. Waver, from the uncertainty of things to be chosen. James 1: for he who hesitates is like the wind; be shaken, from the inconstancy of purposes. Job 4: your hands have strengthened the staggering. Be drunk, from the anxiety of sorrows. Habakkuk 2: drink also, you, and be fast asleep; the cup of the right hand of the Lord shall come round about you. Second he sets forth the manner of the blindness, for he has mingled; that is, as mingled wine he has given to drink, your eyes, namely the prophets. Above, 19: the Lord has mingled in its midst a spirit of dizziness. Third he sets forth the effect of the blindness, because the book of sacred Scripture and the visions of all the prophets they shall not understand. And it shall be to you. Apocalypse 5: I saw in the right hand of him who sat a book. And the Lord said. Here he sets forth the cause of the blindness, namely their own sin: first as to the affections; second as to the intellect, woe to those who are deep. Concerning the first he sets forth two things. First the fault of contempt of God, but his heart, because they cloak it with words, with lips, with human observances. And they feared. Jeremiah 12: you are near to their mouth, and far from their reins. Matthew 15: you have made void the commandment of God for the sake of your traditions. Second, the punishment, therefore behold I, great, according to their own reputation, or formerly. Obadiah: I will destroy the wisdom of the wise, and the prudence of the prudent I will reject: 1 Corinthians 1. Woe to those who are deep. Here he sets forth the sin on the part of the intellect, because they did not believe in the providence of God, that he would know the things that are done concerning us: and concerning this he does two things. First the devising of the error is set forth. Now they said that they escaped God's notice, on account of the depth of the heart, where they turned over their wicked counsels: hence he says, who are deep, Jeremiah 17: the heart of man is deep and unsearchable; who shall know it? And on account of the obscurity of the places in which they carried out their wicked works: hence he says, whose are, John 3: everyone who does evil hates the light. Ecclesiasticus 16: do not say, I shall be hidden from God. Second the just rebuke is set forth, it is perverse. You have not made it, because God knows insofar as he is the cause of the thing. Below, 45: woe to him that contradicts his maker. Below, 64: and now, O Lord, you are our father, but we are clay; and you our fashioner, and we are all the works of your hands. Is it not. Here he foretells the conversion of the Gentiles: and concerning this he does three things. First he foretells the conversion to grace. Lebanon, the Gentiles, because it was a mountain in the land of the Gentiles; into Carmel, into the grace which the Jews had through circumcision, because it is interpreted knowledge of circumcision. Into a forest, that is, into the barrenness in which the Gentiles previously were. Below, 32, the same is found. To sacred knowledge, the deaf, namely the Gentiles, who previously had not heard the words of the law. Matthew 2: the blind see. John 9: I have come into this world for judgment, that those who do not see may see, and those who see may become blind. To spiritual gladness, and they shall add. Psalm 9: I will be glad and exult in you, I will sing to your name, O Most High. Second he assigns the occasion, or reason, of the conversion, from the fall of the Devil: for he has failed who prevailed, through power; the mocker, the deceiver through cunning. Above, 16: the wretch is consumed, from the blindness of the Jewish people: because blindness in part has come upon Israel: Romans 11. Cut down are those who watched: eagerness toward evil. Proverbs 4: for they do not sleep, unless they have done evil. Who to sin, by wicked examples and teachings. Him that reproved, as to the contempt of discipline. Amos 5: they have hated him that reproves in the gate. They have turned aside, as to the vanity of sin, because that which does not attain its end is in vain. Wisdom 5: what has pride profited us, or what has the boasting of riches conferred upon us? Third he sets forth the return of the Jews at the end of the world, therefore thus says; who redeemed, Genesis 11. Not now, that is, in this time, shall he be confounded, with a good confusion. Ecclesiasticus 4: there is a confusion that brings glory; sons, the apostles, murmurers, that is, those who formerly murmured. Above, 27: they that shall go forth with impetus from Jacob, and Israel shall blossom and bud. Or it can be expounded otherwise, of the prosperity which is promised to them once Sennacherib or Nebuchadnezzar has been destroyed. Carmel into a forest; that is, so great shall be the fertility of the land of promise, that the fertility of Carmel shall be reckoned barrenness in comparison to it. The mocker, Sennacherib or Nebuchadnezzar. His sons, the three youths in the furnace of fire: or because their own children shall render the praise of my name, which they themselves did not render in their youth.”

“That make a man an offender for a word,.... Inadvertently spoken, unwarily dropped, without any bad design or ill meaning; or for a word misplaced or misconstrued; or for preaching and professing the word of God, the Gospel of salvation, and adhering to it; which is the true character of the persecutors of good men in all ages: some render the words, "who make a man sin by a word" (e); by their words and doctrines; and so apply it to the false prophets, as Jarchi does; and very well agrees with the Pharisees in Christ's time, who made men to sin, to transgress the word of God, by their traditions. The Targum is, "who condemn the sons of men by their words;'' or for them; particularly for their words of reproof, for which they make them offenders, or pronounce them guilty, as follows: and lay a snare for him that reproveth in the gate; either for just judges, who sat in the gate of the city, and faithfully reproved and punished men for their sins; or for such that had boldness and courage enough to reprove wicked men openly, and before all, for their wickedness, the gate being a public place, where people pass and repass; and such that sin openly should be reproved openly; and particularly the true prophets of the Lord may be referred to, who sometimes were sent to publish their messages, which were frequently reproofs of the people, in the gates of the city; but, above all, Christ seems to be respected, who in the most public manner inveighed against the Scribes and Pharisees for their wickedness, on account of which they sought to entangle him in his talk, and to lay snares for his life; see Mat 22:15, and turn aside the just for a thing of nought; the Targum is, "that falsely pervert the judgment of the innocent;'' that turn away their judgment, decline doing them justice, but condemn them on frivolous pretences, for just nothing at all, what is mere emptiness and vanity: Christ is eminently the "just" One, righteous in himself, and the author of righteousness to others; yet, on account of things for which there were no foundation, and contrary to all justice, he was proceeded against as a criminal. (e) "qui verbie faciunt ut peccent homines", Castalio; "peccare facientes hominem in verbo", Pagninus, Montanus. And to the same sense the Septuagint, V. L. Syr. and Arab.”

“Judges and public officers, who were bound to support order and justice, lent their influence to vice. "To watch" expresses the care of a superior. Heb. 13 : 17. St. Jerome explains it of " demons, who, being themselves wicked, caused all men to sin in word, blaspheming in many points, and subverted, as far as in their power, and led away from justice him who at the gate and in judgment reproved vice."”

“Rather, "Who make a man guilty in his cause" [GESENIUS], that is, unjustly condemn him. "A man" is in the Hebrew a poor man, upon whom such unjust condemnations might be practiced with more impunity than on the rich; compare Isa 29:19, "the meek . . . the poor." him that reproveth--rather, "pleadeth"; one who has a suit at issue. gate--the place of concourse in a city, where courts of justice were held (Rut 4:11; Pro 31:23; Amo 5:10, Amo 5:12). just--one who has a just cause; or, Jesus Christ, "the Just One" [HORSLEY]. for a thing of naught--rather, "through falsehood," "by a decision that is null in justice" [BARNES]. Compare as to Christ, Pro 28:21; Mat 26:15; Act 3:13-14; Act 8:33.”
