“Someone who looks at what is done divinely by the Word and denies the body, or looks at what is proper to the body and denies the Word's presence in the flesh or from what is human, entertains low thoughts concerning the Word … as a Jewish vintner, mixing water with the wine, shall account the cross an offense, or as a Gentile, will deem the preaching folly.”

“And who is sufficient for these things? For we are not as the many, able to corrupt the word of truth and mix the wine, which makes glad the heart of man, with water. [We do not] mix, that is, our doctrine with what is common and cheap, and debased, and stale, and tasteless, in order to turn the adulteration to our profit and accommodate ourselves to those who meet us, and curry favor with everyone. [We do not] become ventriloquists and chatterers, who serve their own pleasures by words uttered from the earth, and sink into the earth, and, to gain the special good will of the multitude, injure in the highest degree, no, ruin ourselves, and shed the innocent blood of simpler souls, which will be required at our hands.”

“Your silver has become dross They would make copper coins and plate them with silver, in order to cheat with them. your wine is diluted with water Your drinks are mixed with water, as is stated in Pesikta (122b). [The word] means ‘mixed,’ although there is no similar word in Scripture to prove it, but the Midrash Aggadah explains (Ecc. 2:2): “Of laughter I said, it makes one mad (מְהוֹלָל)” to mean that it is confused, or mixed up.”

“How is she become a harlot. Here he shows their sin according to the turning away from justice toward one's neighbor: and concerning this he does three things. First he describes the fault; second he threatens the punishment, at the place, Therefore thus saith the Lord; third, the sequel of the punishment, at the place, And I will restore. Concerning the first, first he reproves the sin of the people; second, the sin of the priest, at thy silver; third, the sin of the prince, at thy princes. In the people he reproves two things, aggravating by comparison to their former state: namely, venality by comparison to their former fidelity: whence, how is she become a harlot? Jer. 2: under every leafy tree and upon every high hill thou didst lie down, a harlot: and cruelty by comparison to justice and judgment, which is the execution of justice. Ps. 93: until justice be turned into judgment. Whence he says: but now murderers. Hosea 4: cursing and lying and killing and theft and adultery have overflowed, and blood hath touched blood. The sin of the priest he reproves in two things. In the corruption of the truth of doctrine: whence he says: thy silver is turned into dross. Ps. 11: the words of the Lord are pure words, silver tried by the fire, proved from the earth, refined seven times. Jer. 5: the prophets have prophesied a lie. Second, in the remission of the severity of discipline, which is signified in the wine: for this is the wine which the Samaritan poured in: Luke 10. Whence he says: thy wine. Ezech. 13: woe to them that sew. Thy princes. Here he reproves the sin of the princes: and first he shows them unfaithful in the execution of their office, in that they carry it out for their own advantage and not that of the people. Amos 6: anointed with the best ointment, drinking wine in bowls. Ezech. 34: woe to the shepherds of Israel, that feed themselves. Should not the flocks be fed by the shepherds? And for this he says, faithless. Second he shows them transgressors in the harboring of evildoers: companions of thieves, by defending them and affording them patronage: Hosea 6: as the throats of robber men, the princes of the priests. Prov. 1: son, walk not with them. Third he shows them corrupted in the receiving of gifts. Below, 5: Woe to you that justify the wicked for gifts, and take away the justice of the just from him. Whence he says: they love gifts — received ones; they follow after — things promised or hoped for. Fourth, he shows them unjust in the repulsion of the poor, saying they judge not for the fatherless. Jer. 5: they have not judged the cause of the widow, they have not directed the cause of the fatherless. Therefore thus saith the Lord. Here he threatens the punishment: and first, of the prelates; second, of the subjects, at and I will turn. Concerning the first he sets down three things. First, the power of the one punishing, in authority, saying, the Lord. Malachi 1: if I be the Lord, where is my fear? saith the Lord. In the multitude of ministers: of hosts. Job 25: is there any numbering of his soldiers? In strength, mighty. Job 9: he is wise in heart and mighty in strength: who hath resisted him, and hath had peace? Second he sets down the will of the one punishing. Ah, namely to them, I will comfort myself, since their punishment will be a consolation. Below, 63: the day of vengeance is in my heart, the year of my recompense is come. Third he sets down the cruelty of the punishment: at and I will take vengeance on my enemies: as if to say: I will punish you as enemies. Deut. 32: I will render vengeance to my enemies, and repay them that hate me. And I will turn. Here he threatens the punishment of the subjects. And first is set down the preparation of the one punishing, at and I will turn my hand upon thee to punish thee, which, in sparing, I had held as it were folded up. Job 19: the hand of the Lord hath touched me. Second, the completion of the punishment: I will melt away, by the fire of tribulation, to the pure, until whatever is to be purged is purged. Matt. 5: thou shalt not go out from thence till thou repay the last farthing. Third, the multitude of punishments: I will take away all thy tin: because for every sin, below, 40: she hath received of the hand of the Lord double for all her sins. And I will restore. Here he sets down the sequel of the punishment: and first, as regards those corrected, renewal; second, as regards the obstinate, consumption, at and he shall crush. For by the same fire (as Augustine says) gold is proved, and straw smokes. Concerning the first he does three things. First he promises renewal as regards the amendment of the prelates; second, as regards the restoration of good name, at after this thou shalt be called; third, as regards the observance of justice, at Zion in judgment. He says therefore: I will restore the judges, as regards the secular princes, whose office it is to judge the people, and thy counsellors, that is, the priests, whose office it is to minister the counsels of God to the peoples: Malachi 2: the lips of the priests keep knowledge, and they seek the law at his mouth: because he is the angel of the Lord of hosts: as they were before, as Moses and Joshua, who pleased God. Jer. 3: I will give you pastors according to my own heart, and they shall feed you with knowledge and doctrine. And thou shalt be called, that is, thou shalt recover thy fame, so that thou art called such as thou wast before, the city of the just, that is, in which justice is kept. Below, 62: thou shalt no more be called Forsaken, neither shalt thou any more be called Desolate; but thou shalt be called My will is in her. Zion in judgment, through the execution of justice, shall be redeemed, from those who wrong her; and they shall bring her back in justice; for judgment is to bring back to equality, in which justice consists. Ps. 71: to judge thy people with justice, and thy poor with judgment. Jer. 23: a king shall reign (...) and shall do justice and judgment in the land. And he shall crush. Here is set down the destruction of the obstinate; and concerning this he does three things. First he foretells the destruction; second, the manner of the destruction, at they shall be confounded; third, he takes away the hope of escape, at and thy strength shall be. And since the punishment is ordered against the fault, therefore concerning the first he touches on the fault in two ways. On the part of turning, as regards the crime of idolatry: whence he says, the wicked; and as regards the sin of pleasure and luxury: whence he says, sinners: because men are most prone to such things; against which he ordains the punishment of crushing, wherein a punishment is marked out to match the wrong inflicted. Jer. 17: crush them with a double destruction; as it were for a double sin. Second, on the part of turning away, because they have forsaken the Lord; against which he ordains the punishment of consumption, saying, they shall be consumed; in which he designates the punishment of desertion: for what is consumed goes into nothing, and all things would fall into nothing, unless the hand of the Lord held them together; as Gregory says. Jer. 17: O Lord, all that forsake thee shall be confounded: they that depart from thee shall be written in the earth: because they have forsaken the vein of living waters, the Lord. They shall be confounded. Here he sets down the manner of the destruction: and first, as regards the confusion of sin; second, as regards the taking away of good, at when you shall be. Concerning the first, against idolatry he ordains confusion, saying: they shall be confounded for the idols, that is, on account of the idols. Ps. 96: let them all be confounded that adore graven things: against pleasure, shame, when he says: you shall be ashamed of the gardens, that is, of the pleasurable places, which you had chosen, of your luxury. Rom. 6: what fruit had you in those things, of which you are now ashamed? For confusion regards more the evil; but shame regards the fault. For carnal sins (as Gregory says) are of lesser fault and greater infamy. And the reason is, that they are according to the baser powers, and most material ones: and yet they are innate and connatural and subject to passion. When you shall be. Here is set down the taking away of good: and first, of that which pertains to protection and adornment, which is signified in the taking away of leaves; second, of that which pertains to fruit, at as a garden without water, barren. And in contrast it is said of the just man, Ps. 1: he shall be as a tree which is planted near the running waters. And it shall be. Here he takes away from them the hope of escape: and he sets down three things. First he takes away from them the support of their own strength: whence he says: thy strength shall be as the ash of tow, which is quickly consumed. Ecclus. 21: the congregation of sinners is like tow heaped together. Second, the help of idols, saying: your work, namely of idols, which your hands have wrought, as a spark, which is of no consequence. Deut. 32: where are their gods, in whom they trusted? And yet it is burnt up: whence follows, and it shall be kindled. Below, 50: walk in the light of your fire. Third, the help of men: and there shall be none to quench it. Ezech. 20: the flame of the kindling shall not be quenched, and every face shall be burnt in it, from the south even to the north; and all flesh shall see.”

“Thy silver is become dross,.... Meaning either that such persons, who had the appearance of goodness, looked like genuine silver, were now become reprobate, and, as the wicked of the earth, like dross, Jer 6:30 or that the word of God, which is as silver purified seven times, was now corrupted with false glosses and human traditions, which were as dross: thy wine mixed with water (m); the wine of the divine word, which was mixed and blended with the inventions of men, as before; so the roof of the church's mouth, which is no other than the ministry of the word, is compared to the best wine, Sol 7:9. (m) It being usual to mix water with wine, and drink it, and this being not at all reproachful, but commendable, Gussetius thinks such a version does not express the sense of the words; he therefore thinks that is the same as contracted, which signified "infatuated"; and so the words should be rendered, "thy wine is infatuated into water"; is degenerated, and has lost its spirit and sprightliness, and is become insipid and tasteless. So Jarchi mentions a Midrash, which interprets it by the same word in Ecc 2:2. It is a word only used in this place. Joseph Kimchi says that in the Arabic, language has the signification of mixture, but without giving any instance. Indeed, according to Castel, it is used for the lees of oil.”

“Thy princes and people are degenerate in "solid worth," equivalent to "silver" (Jer 6:28, Jer 6:30; Eze 22:18-19), and in their use of the living Word, equivalent to "wine" (Sol 7:9). mixed--literally, "circumcised." So the Arabic, "to murder" wine, equivalent to dilute it.”

“The complaint now turns from the city generally to the authorities, and first of all figuratively. "Thy silver has become dross, thy drink mutilated with water." It is upon this passage that the figurative language of Jer 6:27. and Eze 22:18-22 is founded. Silver is here a figurative representation of the princes and lords, with special reference to the nobility of character naturally associated with nobility of birth and rank; for silver - refined silver - is an image of all that is noble and pure, light in all its purity being reflected by it (Bhr, Symbolik, i. 284). The princes and lords had once possessed all the virtues which the Latins called unitedly Candor animi, viz., the virtues of magnanimity, affability, impartiality, and superiority to bribes. This silver had now become l'sigim, dross, or base metal separated (thrown off) from silver in the process of refining (sig, pl. sigim, siggim from sug, recedere, refuse left in smelting, or dross: cf., Pro 25:4; Pro 26:23). A second figure compares the leading men of the older Jerusalem to good wine, such as drinkers like. The word employed here (sobe) must have been used in this sense by the more cultivated classes in Isaiah's time (cf., Nah 1:10). This pure, strong, and costly wine was now adulterated with water (lit. castratum, according to Pliny's expression in the Natural History: compare the Horatian phrase, jugulare Falernum), and therefore its strength and odour were weakened, and its worth was diminished. The present was nothing but the dross and shadow of the past.”
