5. Is it such a fast as I have chosen? He confirms the preceding statement, and shows that fasting is neither desired nor approved by God in itself, but so far as it is directed to its true end. He did not wish that it should be altogether abolished, but the improper use of it; that is, because they believed the worship of God to consist in it, and by neglecting or even despising true godliness, thought that bodily exercise was enough; just as hypocrites always put forward external ceremonies, as if they were satisfactions to appease God.

Again, because men, through their rashness, define what is the worship of God, he expressly refers us to his own will, that we may not suppose that he approves of everything which our own judgment pronounces to be right. Although men are well pleased with themselves, and swell with astonishing haughtiness, and indulge in insolent boasting, the Lord rejects and abhors them, because he claims for himself alone the right to “choose.” Now, “to choose” a thing is of the same import as “to take pleasure in it.”

And hanging his head like a bulrush. He says that he is not delighted if a man passes a day in hunger, and then walks with a sad and downcast look. The Prophet employs all appropriate metaphor; because the bulrush, though it is straight, is easily bent. So hypocrites bend themselves, and bow down the head, as if under the influence of oppressive leanness, or display some empty appearance of humility. The Prophet therefore intended to censure superstitious attitudes, in which hypocrites imagine that there is some holiness.

And spread sackcloth and ashes. These things also were added to fasting, especially when they made solemn professions of repentance; for they clothed themselves with “sackcloth,” and threw “ashes” on their head. (Joel 1:13) Now, such an exercise was holy and approved by God; and we see that the prophets, while they exhort the people to repentance, cry aloud for “sackcloth and ashes.” But as we have said that fasting is not here condemned on its own account, so Isaiah does not condemn those outward ceremonies, but reproves hypocrites for separating them from reality.

If it be asked, Are “sackcloth” and “ashes” suitable to our time? I reply, they are indifferent matters, which may be used for edification; but in the light of the Gospel, which has brought liberty to us, we have no need of such figures. At the same time, we should attend to the difference between Eastern nations, which make use of a great abundance and variety of ceremonies, and Western nations, whose habits are far more simple. If we wished to imitate the former, it would be nothing else than to enact the part of apes, or of stage­players. Yet there is nothing to hinder those who intend to confess their guilt, from wearing soiled and faltered garments, after the manner used by suppliants. ¹²¹¹²¹     “Selon la coustume des criminels qui demandent misericorde.” “According to the custom of criminals who implore mercy.”

A day acceptable to Jehovah. Hence it is evident that to solemn prayer, when a holy assembly was held, there was added fasting; for fasting, as we have already said, is an appendage to prayer; as we see that it was added to prayer by Christ himself. (Matthew 17:21) It is not appointed, therefore, for its own sake, but is directed to a different end.

6. Is not this the fast which I have chosen? The Prophet shows what are the real duties of piety, and what God chiefly recommends to us; namely, to relieve those who are wretched and pressed with a heavy burden. But the Prophet appears to abolish fasting universally, when, in place of it, he enumerates those works which are most highly acceptable to God. I reply, fasting is approved when it is accompanied by that love which we owe to our fellow­men; and therefore the Prophet directs that we shall be tried by this principle, that our consciences be entire and pure, that we exercise mutual kindness towards each other; for if this order prevail, then fasting, which shall be added to it, will be pleasing and acceptable to God. But here he does not at all mention purity of heart. I reply, it is described by works, as by its fruits, from which it is easily seen what kind of heart we have. Next, he enumerates the duties of the Second Table, under which, as we have elsewhere seen, by a figure of speech in which a part is taken for the whole, he includes the whole observation of the Law; for it would not be enough to assist our neighbor by kind offices, if at the same time we despised God. But we must observe the Prophet’s design; because the love which we owe to our neighbors cannot be sincerely cultivated, unless when we love them in God. In order to make trial of our fear of God, he demands these as more immediate signs, if we live justly, inoffensively, and kindly with each other. Besides, he was not satisfied with outward appearance; and indeed the love of our neighbor does not thrive where the Spirit of God does not reign; and therefore Paul includes it in the enumeration of “the works of the Spirit.” (Galatians 5:22) Thus when the observation of the Law is spoken of, not only outward works, but likewise the dispositions of the heart, must be taken into the account.

To loose wicked bindings. Some explain it to mean “sinful thoughts,” by which the hearts of men are entangled. But Isaiah appears to me to have had another object in view, namely, that hypocrites are exceedingly cruel in distressing the poor, and lay heavy burdens upon them. He therefore calls them “bonds,” or “bindings,” or, as we commonly say, “oppressions.” Of the same import is what he adds, to undo the heavy burdens, under the weight of which the poor groan and are overwhelmed. he again adds, “to let the oppressed go free,” and expresses the same thing in a variety of words. Thus the Prophet does not define what is meant by “fasting,” but shows what the Lord requires in the first place and chiefly, and in what manner our obedience can be approved by him, and what ought to be the dispositions of those who endeavor to fast in a right manner.

7. Is it not to break thy bread to the hungry? He goes on to describe the duties of love of our neighbor, which he had described briefly in the preceding verse; for, having formerly said that we must abstain from every act of injustice, he now shows that we ought to exercise kindness towards the wretched, and those who need our assistance. Uprightness and righteousness are divided into two parts; first, that we should injure nobody; and secondly, that we should bestow our wealth and abundance on the poor and needy. And these two ought to be joined together; for it is not enough to abstain from acts of injustice, if thou refuse thy assistance to the needy; nor will it be of much avail to render thine aid to the needy, if at the same time thou rob some of that which thou bestowest on others. Thou must not relieve thy neighbors by plunder or theft.; and if thou hast committed any act of injustice, or cruelty, or extortion, thou must not, by a pretended compensation, call on God to receive a share of the plunder. These two parts, therefore, must be held together, provided only that we have our love of our neighbor approved and accepted by God.

By commanding them to “break bread to the hungry, ¹²²¹²²     Grotius says that “the bread in those countries was such as could be easily ‘broken,’ [like the thin cakes which are still common in the East]; and that to ‘break,’ consequently, meant to ‘impart,’ or to distribute. The phraseology is borrowed from the breaking of the bread which is distributed by the head of a family to the domestics at his table.” — Rosenmuller. he intended to take away every excuse from covetous and greedy men, who allege that they have a right to keep possession of that which is their own. “This is mine, and therefore I may keep it for myself. Why should I make common property of that which God has given me?“ He replies, “It is indeed thine, but on this condition, that thou share it with the hungry and thirsty, not that thou eat it thyself alone.” And indeed this is the dictate of common sense, that the hungry are deprived of their just right, if their hunger is not relieved. That sad spectacle extorts compassion even from the cruel and barbarous. He next enumerates various kinds, which commonly bend hearts of iron to συμπάθειαν fellow­feeling or compassion; that the savage disposition of those who are not moved by feeling for a brother’s poverty and necessity may be the less excusable. At length he concludes —

And that thou hide not thyself from thine own flesh. Here we ought to observe the term flesh, by which he means all men universally, not one of whom we can behold, without seeing, as in a mirror, “our own flesh.” It is therefore a proof of the greatest inhumanity, to despise those in whom we are constrained to recognize our own likeness.

8. Then shall break forth as the dawn ¹²³¹²³     “As the pillar of the dawn bursts through the clouds.” ­ Jarchi. thy light. The Prophet shows that God is not too rigorous, and does not demand from us more than what is proper; and that hypocrites complain of him without cause, when they accuse him of excessive severity. When their works are condemned, they murmur, and reply that God can never be satisfied, that they do not know what they should do, or what course they should follow. He replies that he demands nothing else than a pure and honest heart, that is, an upright conscience; that if they have this, God will graciously receive them, and will bear testimony to their holiness, and will bestow every kind of blessing on those whose faults he justly chastises; and lastly, that there is no reason why they should murmur at him as excessively stern and harsh, because they will find him to be kind and bountiful when they shall lay down all hypocrisy, and devote themselves sincerely to his service.

We should observe the particle then; for it means that hypocrites, on the contrary, are very far from the true worship of God, though they wish to be reckoned very holy persons. But he holds them to be fully convicted, when he shows from their works that they neither worship nor fear God. By the word light he means prosperity, as by the word “darkness” is meant a wretched and afflicted life; and this mode of expression occurs frequently in Scripture.

And thy health. By “health” he means prosperity and safety, as we shall afterwards see in another passage, because the wounds inflicted by the hand of God on account of their sins had brought the people so low that they wasted away like a sick man under terrible disease. No kind of disease is more severe than to be pursued by God’s righteous vengeance, or consumed under his curse.

Righteousness shall go before thy face. “Righteousness” may be taken in two senses, either for the testimony of “righteousness,” or for good order; because God will put an end to the confusion, and will restore everything to its proper place. Thus the former meaning amounts to this, “When God shall be pacified towards thee, the testimony of thy righteousness shall be visible before God and men, as if some herald went before thee.” There are some who prefer to expound the word “righteousness” as meaning just government, which is the gift of God, and a token of his kindness as a Father; and we have seen that this word is sometimes used in that sense by Hebrew writers. But the latter clause which follows, And the glory of Jehovah will gather thee, leads me to prefer the former exposition, “Thy righteousness shall go forth;“ that is, “All shall acknowledge thee to be holy and righteous, though formerly thou wast guilty and convicted. So shalt thou also be adorned with the glory of the Lord, though formerly thou wast loaded with reproaches.” For we are reproached and disgraced, while we suffer the punishment of our sins.

9. Then shalt thou call. Isaiah follows out what he had formerly begun, that everything shall prosper well with the Jews, if they shall be just and inoffensive and free from doing wrong to any one, so that it shall manifest their piety and religion. He pronounces what is said by Hosea, (Hosea 6:6) and repeated by Christ, that “mercy shall be preferred to sacrifice.” (Matthew 9:13; 12:7) Thus after having spoken of the duties which men owe to one another, and testified that it shall be well with those who shall perform those duties, he adds, “Then shalt thou call, and the Lord will listen to thee.” The chief part of our happiness is, if God listen to us; and, on the other hand, nothing could be more miserable than to have him for an enemy. In order to try our faith, he attributes to our prayers what he bestows willingly and by free grace; for if he always bestowed his blessings while we were asleep, the desire to pray would become utterly cold, and indeed would cease altogether; and so the kindness of God would be an encouragement to slothfulness. Although he anticipates us by his free grace, yet he wishes that our prayers for his blessings should be offered, and therefore he adds, Thou shalt cry, and he shall say, Behold, here I am. This promise likewise contains an exhortation, that we may not lie idle. When he says that he is present, this indeed is not visible to our eyes; but he gives a practical declaration that he is near and reconciled to us.

If thou shalt take away from the midst of thee the yoke. In the latter part of the verse he again repeats that God will be reconciled to the Jews if they repent. Under the word “yoke” he includes all the annoyances that are offered to the poor; as if he had said, “If thou shalt cease to annoy thy brethren, and shalt abstain from all violence and deceit, the Lord will bestow upon thee every kind of blessing.”

And the pointing of the finger. ¹²⁴¹²⁴     “Grotius thus explains this clause, ‘If thou shalt cease to point at good men with “the disreputable finger,” (as Persius calls it,)and to mock at their simplicity.’ In like manner Juvenal says, (Sat. 10:52)
   Quum fortunic ipsi minaci
Mandaret ]aqueum, mediumque ostenderet unguem.
   On this passage scholiasts observe, that it was an ancient custom, when any person was the object of scorn, or was treated with marked contempt or disgraceful reproach, to point at him by holding out the middle finger.” ­ Rosenmuller. This includes every kind of attack; for we are said to “point the finger,” when we threaten our neighbors, or treat them cruelly, or offer any violence.

And speech of vanity, or unprofitable speech. This is the third class of acts of injustice, by which we injure our neighbor when we impose upon him by cunning and deceitful words or flatteries; for every iniquity consists either of concealed malice and deceit, or of open violence.
