12. And the Lord of hosts called. The wicked obstinacy of the people is exhibited by the Prophet with additional aggravations. What left them altogether without excuse was the fact, that while they were exposed to so great dangers, they despised the godly remonstrances of the prophets, and rejected the grace of God, when he wished to heal and restore them. It is a proof of consummate depravity, when men have so completely laid aside all feeling that they fearlessly despise both instruction and chastisements, and obstinately “kick against the pricks,” (Acts 9:5,) and this makes it evident that they have been “given over to a reprobate mind.” (Romans 1:28.)

When he says, that “the Lord called” them, this may be explained in two ways; for although the Lord does not speak, still he calls loudly enough by stripes and chastisements. Let it be supposed that we are destitute of all Scripture, of prophets, teachers, and advisers, still he instructs us by distresses and afflictions, so that we may state, in a few words, that every chastisement is a call to repentance. But, unquestionably, the Prophet intended to express something more, namely, that in despising godly warnings, they did not scruple to treat with scorn God’s fatherly invitation.

In that day. There is great weight also in mentioning the day of affliction, when danger threatened them, for they were admonished at the same time by the word and by strokes. The signs of God’s anger were visible, the prophets uttered incessant cries, and still they became no better.

To baldness and girding with sackcloth. When he mentions sackcloth and baldness, ⁸⁶⁸⁶    {Bogus footnote} he employs the signs themselves to describe repentance; for repentance does not consist in sackcloth or haircloth, ⁸⁷⁸⁷    {Bogus footnote} or anything outward, but has its place in the heart. Those who sincerely repent are displeased with themselves, hate sin, and are affected with such a deep feeling of grief, that they abhor themselves and their past life; but as this cannot be done without, at the same time, making itself known by confession before men, on this account he describes the outward signs by which we give evidence of our conversion. Now, these things were at that time cast away among the Jews, when they made public declarations of repentance. The Prophet therefore means that they were called to repentance, to humble themselves before God, and to exhibit the evidences of repentance before men. Of themselves, indeed, the signs would not be sufficient, for repentance begins at the heart; and Joel gives warning to that effect,

“Rend your hearts, and not your garments.” (Joel 2:13.)

Not that he wished signs to be laid aside, but he shewed that they are not sufficient, and that of themselves they are not acceptable to God.

Hence infer what is our duty, when the tokens of God’s anger are visible to us. We ought to declare publicly our repentance, not only before God, but also before men. The outward ceremonies, indeed, are of little consequence, and we are not commanded to wear sackcloth or to pull out our hair; but we must practice honestly and sincerely what is actually meant by these signs, disapprobation and confession of our guilt, humility of the heart, and reformation of the life. If we do not confess that we are guilty, and that we deserve punishment, we shall not return to a state of favor with God. In short, as culprits allow their beards to grow, and wear tattered clothes, in order to affect the hearts of the judges, so we ought to betake ourselves as suppliants to the mercy of God, and make a public declaration of our repentance.

But here we ought also to observe the usefulness of outward signs of repentance; for they serve as spurs to prompt us more to know and abhor sin. In this way, so far as they are spurs, they may be called causes of repentance; and so far as they are evidences, they may be called effects. They are causes, because the marks of our guilt, which we carry about us, excite us the more to acknowledge ourselves to be sinners and guilty; and they are effects, because, if they were not preceded by repentance, we would never be induced to perform them sincerely.

13. And, behold, joy and gladness. The Prophet does not here find fault with joy viewed in itself; for we see that Paul exhorts the godly to true joy, the “joy” which is “in the Lord,” (Philippians 4:4;) but now he censures the joy which is opposite to that sadness which commonly springs from repentance, of which Paul also speaks. (2 Corinthians 7:10.) No man can be under the influence of repentance and of a sincere feeling of the wrath of God, without being led, by the grief which accompanies it, willingly to afflict himself. The joy which is opposite to this grief is therefore sinful, because it proceeds from brutish indifference, and is justly blamed, since the Lord curses it. (Luke 6:25.)

Slaying oxen and killing sheep. From what has been said, it is easy to see the reason why he censures them for “slaying oxen and killing sheep.” These things are not in themselves sinful, and are not displeasing to God; but as fasting is a part of a solemn declaration of repentance, which we make before men, so to slay cattle for feasting, when we ought to fast, is a proof of obstinacy and contempt of God; for in this way men despise God’s threatenings, and encourage themselves in their crimes.

Such is the statement which Isaiah intended to make in general terms. But it is absurd in the Papists to think of drawing from it an approbation of abstinence from eating flesh. Why do they not also include what the Apostle adds about wine? They are so far from abstaining from the use of wine, that they freely indulge in drinking it, as a compensation for the want of flesh. But let us pass over these absurdities. Isaiah does not absolutely condemn the use of flesh or the drinking of wine, but he condemns the luxury and wantonness by which men are hardened in such a manner that they obstinately set aside God’s threatenings, and treat as false all that the prophets tell them.

This ought to be carefully observed, for we do not always wear sackcloth and ashes; but we cannot have true repentance without making it manifest by the fruits which it must unavoidably produce. In short, as he had described repentance by its signs, so he marks out obstinacy by its signs; for as by fasting and other outward acts we testify our repentance, so by feasting and luxury we give proofs of an obstinate heart, and thus provoke more the wrath of God, in a similar manner to what we read about the days of Noah. (Genesis 6:5; Matthew 24:38, 39; Luke 17:27.) After having described intemperance and luxury in general terms, he particularly mentions eating and drinking, in which the Jews indulged to such an extent as if they had been able, in some measure, to combat the wrath of God, and to obliterate the remembrance of his threatening.

For to-morrow we shall die. This clause shews plainly enough why the Prophet complained so loudly about eating flesh and drinking wine. It was because all the threatenings uttered by the prophets were turned by them into a subject of jesting and laughter. It is supposed that Paul quotes this passage, when, in writing to the Corinthians, he uses nearly the same words. (1 Corinthians 15:32.) But I am of a different opinion; for he quotes the opinion of the Epicureans, who lived for the passing day, and gave themselves no concern about eternal life, and therefore thought that they should follow their natural disposition, and enjoy pleasures as long as life lasted. Isaiah, on the other hand, relates here the speeches of wicked men, who obstinately ridiculed the threatenings of the prophets, and could not patiently endure to be told about chastisements, banishment, slaughter, and ruin. They employed the words of the prophets, and in the midst of their feasting and revelry, turned them into ridicule, saying, in a boasting strain, “To-morrow we shall die. If the prophets tell us that our destruction is at hand, let us pass the present day, at least, in cheerfulness and mirth.”

Thus, obstinate minds cannot be struck with any terror, but, on the contrary, mock at God and the prophets, and give themselves up more freely to licentiousness. It certainly was frightful madness when, through indignation and wrath, they quoted with bitter irony the words which not only ought to have affected their minds, but ought to have shaken heaven and earth. Would that there were not instances of the same kind in the present day! For whenever God threatens, the greater part of men either vomit out their bitterness, or sneeringly ridicule everything that has proceeded from God’s holy mouth.

14. This is revealed. ⁸⁸⁸⁸    {Bogus footnote} As if he had said, “Do you think that you can escape punishment for your wantonness, when God calls you to repentance?” It might be thought that here the Prophet says nothing that is new; for undoubtedly all things are known to God. But he adds this for the purpose of shaking off the indolence of men, who never would rise so fiercely against God, if they did not think that they could deceive him; for whosoever knows that God is his witness, must also acknowledge that God is his judge. Hence it follows that wicked men, in their wantonness, rob God of his power; and therefore it is not without reason that they are summoned to his tribunal, that they may know that they must render an account to him.

If this iniquity shall be forgiven you till you die. He adds a dreadful threatening, that this wickedness shall never be forgiven. In the Hebrew language, the conditional particle, if, contains a denial, as if the Lord had said, “Do not think that I am true, or that I have any divine perfections, if I do not take vengeance on so great wickedness.” The reason why the Jews, in their oaths, reserve something which is not expressed, is to accustom us to deeper reverence in this matter; for we entreat God to be our Judge and avenger if we speak falsely, and therefore we ought to restrain ourselves, so as not to make oaths at random. Here Isaiah states generally, that nothing is so displeasing to God as impenitence, by which, as Paul says, (Romans 2:5,) we “heap up for ourselves the treasures of God’s wrath,” and shut out all hope of pardon.
