They that were sanctified, and thought themselves clean in the gardens behind the gate within, they that did eat swine’s flesh, and the abomination, and the mouse: they shall be consumed together, saith the Lord.

The feminine form agrees with אשרה grove, while the masculine form אחד of the Ketib refers to עץ tree; for every grove consists of trees. In the midst.

“Thus says the Lord. Here he determines the manner of the execution of the sentence already given: and first specifically as regards the Jews; second universally as regards all: but I, their works and thoughts. The first is divided into two: in the first he excludes false confidence; second he sets forth and determines the sentence given, as to the manner of its execution: Hear the word of the Lord. Concerning the first there are two parts. First he excludes false confidence in the holiness of the temple, showing that the temple is not the place of God: both from the greatness of God, who fills all things — whose seat heaven is called, because it shares abundantly in his goodness, just as a seat holds the greater part of the one sitting; while earth is his footstool, because the earth shares least in his goodness, just as the outermost part reaches only to the footstool — or by heaven the saints are meant, and by earth the earthly-minded. 3 Kings 8: if heaven and the heaven of heavens do not contain you. Jeremiah 23: I fill heaven and earth. Acts 17: not in the hand-made things of the temple. Then from rest: because each thing rests in the place that is its own place; but God does not rest in anything, rather all things rest in him, as made by him. And what is his place? Above, ch. 40: lift up on high. And he gives a useful remedy: but to whom — the poor one, that is, the humble man who considers himself small as to the present; the contrite, as to past sins; the trembling, as to his resolve concerning what is to be done in the future. Ecclesiasticus 15: his eyes are upon those who fear him. Second, he excludes the confidence they had conceived from the rite of sacrifices: and first he sets down their reprobation: he who sacrifices an ox — as if he were to say: their sacrifices are so abominable, as if they were doing something against the law, because they were offering the same things to idols. He who blesses — that is, praises and venerates. Above, ch. 1: do not offer sacrifice any more. Second, he shows the reason for the reprobation, first setting down their fault: they have chosen all these things — namely, the sacrifices — walking in their own ways, evil ones. Proverbs 2: they rejoice when they have done evil, and exult in the worst of things. Second, he threatens punishment: hence, and I — Proverbs 3: he himself will mock the mockers. Job 3: the fear that I feared has come upon me, and what I dreaded has happened to me. Third, he charges the sinners with hardness of heart: because I called — Proverbs 1: I called, and you refused. Hear the word of the Lord. Here he carries out the manner of executing the sentence already given: and first as to the rewards of the good; second as to the punishments of the wicked: and it shall be known. The first is in two parts. First he rouses attention: you who tremble, out of reverence for his words. Ecclesiasticus 2: you who fear the Lord, believe in him. Second, he pursues the promise: and first as to vengeance upon the mockers, setting down their mockery: your brothers have said. Let him be glorified — as if to say: let the glory of the Lord appear, which you expect — as if to say: it will never appear. Above, ch. 5: he will come quickly and swiftly, he will not fail nor grow weary in it. And foretelling their confusion: but they shall be confounded, in this way: a voice of the people, fearing; a voice of the Lord, as to the tumult of enemies. Zephaniah 1: the voice of the day of the Lord is bitter. Second, he carries out the promise as to the abundance of good things: and first as to the reuniting of the people, setting down the promise: before she was in labor — that is, suddenly, and at once, the children of Jerusalem shall be gathered to her, just as if a woman should suddenly bring forth a son, with no labor going before. Above, ch. 37: the children have come as far as the birth. Mystically it is expounded of the childbearing of the Blessed Virgin, and of the childbearing of the Church in the conversion of the faithful, and of the bringing-forth of the eternal generation. And he introduces a question of wonder: who has ever heard such things? Above, ch. 49: who has begotten for me? And he sets down the answer in the person of the Lord: shall not I myself bring forth? — gathering the Jews, or converting the faithful, or the Son from eternity. Similarly, Psalm 93: he who planted the ear, shall he not hear? Or he who formed the eye, does he not consider? And these arguments hold, if that which is of perfection in creatures is attributed to him, with everything that belongs to imperfection removed. Second, he promises immense consolation to those gathered. And first he invites others to rejoice with them: rejoice with Jerusalem — in her, as in the object of joy — setting down the condition of those who rejoice together, as to affection: you who love. Canticle of Canticles 5: eat, O friends, and drink, and be inebriated, dearest ones. As to the sign of affection: you who mourn. Matthew 5: blessed are they who mourn, for they shall be comforted. And the fruit of that shared rejoicing, as to the sharing of gladness, or of peace: that you may suck — Canticle of Canticles 1: your breasts are better than wine. As to the sharing of glory: that you may milk it out, as those who milk out milk. Job 22: then you shall abound in delights over the Almighty. Second, he promises a copious bestowal of peace: for thus says the Lord: I will turn — so that it may be called an overflow, like a river which, though it comes down with great force, does not overflow. And of glory, and as it were a torrent. Above, ch. 48: it would have been made like a river. Third, he promises the full reception of consolation. First as to the administering of the nations: which you shall suck — unto the glory of the nations, because the kings of the nations themselves shall comfort you, and shall sustain you. Hence there follows, at the breasts. Mystically he speaks of the apostles, who rejoiced in the glory of the nations swiftly converted, and carried them, as it were, to the breasts by gentle admonitions. Above, ch. 60: you shall suck milk. Second, as to the divine protection: as if to someone, a mother. Hebrews 12: you have forgotten the consolation. Third, as to the enjoyment of good things: you shall see — the good things given you by God; your bones — you who in adversity were like dry bones. Ezekiel 37: dry bones, hear the word of the Lord. Or, you shall see the divine essence. Ecclesiastes 11: light is sweet, and it is delightful for the eyes to see the sun. Bones, unto the resurrection. And it shall be known. Here he promises punishments to the wicked: and first he threatens punishment, setting down the indignation of the judge: the hand, afflicting the wicked among his servants. Or, the hand of consolation, among his servants, through its effect. Above, ch. 27: there is no indignation in me. He also sets down the greatness of the punishment: for behold, the Lord — in fire, by which the city was to be burned, or by which the world was to be purged. Chariots — the army of the Chaldeans, in which God comes, as it were; or the Angels who will come with him to judgment. Psalm 96: fire shall go before him. Amos 9: they shall perish by the sword of God. He also sets down the multitude of those punished: they shall be multiplied. Above, ch. 34: for the victim of the Lord is in Bosra, and a great slaughter in the land of Edom. Second, he reproaches their guilt: who were sanctifying themselves, thinking to cleanse themselves from uncleanness by waters, or even by the sacrifices of idols, in the gardens, in which they worshipped idols, or gave themselves over to pleasure, after one, coupling with women after the manner of beasts. Or, behind the door — literally, the mouse, the dormouse, against the law, Leviticus 11. Above, ch. 65: they eat swine's flesh, and unclean broth. But I. Here he pursues the manner of the discernment as regards all in common: and first he proclaims the universal judgment: their works and thoughts — judging, as it were, for both together; I come, on the day of judgment. Or, the various kingdoms of your enemies, and destroying the wicked among you. They shall come, to Jerusalem after your return, or to judgment, or to the faith. Joel 3: behold, I will raise them up out of the place in which you sold them. Second, he sets down the summons: and I will set among them — that is, among the Jews who shall be with Zerubbabel and the other leaders — a sign, the edict of Cyrus, to the nations, to which the Jews had been scattered; to Lydia, those who hold the arrow, because they are good archers; my glory, which shall appear in your deliverance. Above, ch. 11: he shall lift up a sign among the nations. Or, he sets the sign of the cross among the apostles, that all may be turned to God, as it were preparing them for judgment. Third, he sets down the preparation of those who are to be judged: and first as to the good; second as to the wicked: and they shall go forth, and shall see. The first is in two parts. First, as to the Jews, setting down their honorable return: they shall bring them on horses — by which are signified the aids which those returning had from the Gentiles. Baruch 5: the Lord shall bring these to you. Or there are signified the various conditions of those who are converted to the faith, as the Gloss expounds. Second, the exaltation of their return, first as to dignity: and I will take — which was fulfilled literally in the Jews, and also in the apostles. Above, ch. 61: you shall be called the priests of the Lord; it shall be said of you, ministers of our God. Second, as to the preservation of their offspring: for as the new heavens, as above, ch. 65 — so shall it stand, forever. Jeremiah 31: if these laws shall fail before me, says the Lord, then the seed of Israel also shall fail. Or, the saints shall stand forever, renewed like heaven and earth. Third, as to the duration of their glory: and it shall be month — as though month shall succeed month, and feast shall succeed feast, in your prosperity. Above, ch. 29: year has been added to year, and the solemnities have run their course. Mystically, the Church after the end; spiritual rest after carnal. Second, as to the Gentiles: and all shall come — because from the various nations they came to Jerusalem to worship the Lord. Psalm 85: all the nations shall come and shall adore before you, O Lord. Or, on the day of judgment: and they shall go forth. Here he sets down the second judgment, as regards the wicked: and first the outflow of the punishment: and they shall go forth, coming to Jerusalem, and they shall see, in the ancient tombs, and in the fields, the bones of their dead fathers. Above, ch. 34: their slain shall be cast out, and from their carcasses a stench shall rise. Or, the saints shall see the damned falling into damnation. Second, he sets down the duration of the punishment: their worm — of conscience, by which even the dead shall be tormented; and fire — of hell. Judith 16: he will give fire and worms into their flesh. Third, the delight taken in these punishments, as regards those who see them: and they shall be unto satiety to all flesh — that is, to the saints. Psalm 57: the just shall rejoice when he shall see the revenge. From these punishments may he free us, who has granted both to begin and to complete. And thus ends the sentence and the literal exposition on Isaiah according to Brother Thomas Aquinas, which Brother Iacobinus of Asti, of the province of Lombardy, at that time a student in the general house of studies at Naples, transcribed into legible letters, completing the authorities. He also arranged collations at certain places upon each of the lectures, and this he did for the benefit of the friars of our order, and that copies of the said writings might be had. Therefore, praise be to him who granted both to begin and to complete. Amen.”

“Within the court, or gardens, where they purified themselves, foolishly supposing that this would remove their crimes, as the pagans did. (St. Jerome) (Tertullian, Bapt. v.) — Instead of gate, St. Jerome wrote unam, “one,” moon or Hecate, which is obviously derived from Hebrew Achat, chap. lvii. 8., and lxv. 11. Chaldean, Syriac, &c., “gardens, one after another with those who eat,” &c. — Mouse, or “field-rat,” (Bochart) all declared unclean; (Leviticus xi. 7, 29.; Calmet) or, “the dor-mouse,” (St. Jerome) which was looked upon as a delicacy by the Romans. (Varro iii. 15.; Pliny, [Natural History?] xxxvi. 1.)”

“in . . . gardens--Hebrew and the Septuagint rather require, "for (entering into) gardens," namely, to sacrifice there [MAURER]. behind one tree--rather, "following one," that is, some idol or other, which, from contempt, he does not name [MAURER]. VITRINGA, &c., think the Hebrew for "one," Ahhadh, to be the name of the god; called Adad (meaning One) in Syria (compare Act 17:23). The idol's power was represented by inclined rays, as of the sun shining on the earth. GESENIUS translates, "following one," namely, Hierophant ("priest"), who led the rest in performing the sacred rites. in . . . midst--namely, of the garden (see on Isa 65:3-4). mouse--legally unclean (Lev 11:29) because it was an idol to the heathen (see on Isa 37:36; Sa1 6:4). Translate, "the field mouse," or "dormouse" [BOCHART]. The Pharisees with their self-righteous purifications, and all mere formalists, are included in the same condemnation, described in language taken from the idolatries prevalent in Isaiah's times.”

“The judgment predicted here is a judgment upon nations, and falls not only upon the heathen, but upon the great mass of Israel, who have fallen away from their election of grace and become like the heathen. "They that consecrate themselves and purify themselves for the gardens behind one in the midst, who eat swine's flesh and abomination and the field-mouse-they will come to an end together, saith Jehovah." The persons are first of all described; and then follows the judgment pronounced, as the predicate of the sentence. They subject themselves to the heathen rites of lustration, and that with truly bigoted thoroughness, as is clearly implied by the combination of the two synonyms hammithqaddeshı̄m and hammittahărı̄m (hithpael with an assimilated tav), which, like the Arabic qadusa and tahura, are both traceable to the radical idea ἀφορίζειν. The אל of תונּגּה־לא is to be understood as relating to the object or behoof: their intention being directed to the gardens as places of worship (Isa 1:29; Isa 65:3), ad sacra in lucis obeunda, as Shelling correctly explains. In the chethib בּתּוך אחד אחר, the אחד (for which we may also read אחד, the form of connection, although the two pathachs of the text belong to the keri) is in all probability the hierophant, who leads the people in the performances of the rites of religious worship and as he is represented as standing in the midst (בּתּוך) of the worshipping crowd that surrounds him, 'achar (behind, after) cannot be understood locally, as if they formed his train or tail, but temporally or in the way of imitation. He who stands in their midst performs the ceremonies before them, and they follow him, i.e., perform them after him. This explanation leaves nothing to be desired. The keri, 'achath, is based upon the assumption that 'achad must refer to the idol, and substitutes therefore the feminine, no doubt with an allusion to 'ăshērâh, so that battâvekh (in the midst) is to be taken as referring not to the midst of the worshipping congregation, but to the midst of the gardens. This would be quite as suitable; for even if it were not expressly stated, we should have to assume that the sacred tree of Astarte, or her statue, occupied the post of honour in the midst of the garden, and 'achar would correspond to the phrase in the Pentateuch, אחרים אלהים אחרי זנה. But the foregoing expression, sanctificantes et mundantes se (consecrating and purifying), does not favour this sense of the word 'achar (why not ל = לכבוד?), nor do we see why the name of the goddess should be suppressed, or why she should be simply hinted at in the word אחת (one). אחד (אחד) has its sufficient explanation in the antithesis between the one choir-leader and the many followers; but if we take 'achath as referring to the goddess, we can find no intelligible reason or object. Some again have taken both 'achad and 'achath to be the proper name of the idol. Ever since the time of Scaliger and Groitus, 'achad has been associated with the Phoenician ̓́Αδωδος βασιλεὺς θεῶν mentioned by Sanchuniathon in Euseb. praep. ev. 1, 10, 21, or with the Assyrian sun-god Adad, of whom Macrobius says (Saturn. 1, 23), Ejus nominis interpretatio significat unus; but we should expect the name of a Babylonian god here, and not of a Phoenician or Assyrian (Syrian) deity. Moreover, Macrobius' combination of the Syrian Hadad with 'achad was a mere fancy, arising from an imperfect knowledge of the language. Clericus' combination of 'achath with Hecate, who certainly appears to have been worshipped by the Harranians as a monster, though not under this name, and not in gardens (which would not have suited her character), is also untenable. Now as 'achath cannot be explained as a proper name, and the form of the statement does not favour the idea that 'achar 'achath or 'achar 'achad refers to an idol, we adopt the reading 'achad, and understand it to refer to the hierophant or mystagogue. Jerome follows the keri, and renders it post unam intrinsecus. The reading post januam is an ancient correction, which is not worth tracing to the Aramaean interpretation of 'achar 'achad, "behind a closed door," and merely rests upon some rectification of the unintelligible post unam. The Targum renders it, "one division after another," and omits battâvekh. The lxx, on the other hand, omits 'achar 'achad, reads ūbhattâvekh, and renders it καὶ ἐν τοῖς προθύροις (in the inner court). Symmachus and Theodoret follow the Targum and Syriac, and render it ὀπίσω ἀλλήλων, and then pointing the next word בּתוך (which Schelling and Bttcher approve), render the rest ἐν μέσω ἐσθιόντων τὸ κρέας τὸ χοιρεῖον (in the midst of those who eat, etc.). But אכלי commences the further description of those who were indicated first of all by their zealous adoption of heathen customs. Whilst, on the one hand, they readily adopt the heathen ritual; they set themselves on the other hand, in the most daring way, altogether above the law of Jehovah, by eating swine's flesh (Isa 65:4) and reptiles (sheqets, abomination, used for disgusting animals, such as lizards, snails, etc., Lev 7:21; Lev 11:11), (Note: See Levysohn, Zoologie des Talmuds, pp. 218-9.) and more especially the mouse (Lev 11:29), or according to Jerome and Zwingli the dormouse (glis esculentus), which the Talmud also mentions under the name דברא עכברא (wild mouse) as a dainty bit with epicures, and which was fattened, as is well known, by the Romans in their gliraria. (Note: See Levysohn, id. pp. 108-9. A special delicacy was glires isicio porcino, dormice with pork stuffing; see Brillat-Savarin's Physiologie des Geschmacks, by C. Vogt, p. 253.) However inward and spiritual may be the interpretation given to the law in these prophecies, yet, as we see here, the whole of it, even the laws of food, were regarded as inviolable. So long as God Himself had not taken away the hedges set about His church, every wilful attempt to break through them was a sin, which brought down His wrath and indignation.”
