58. True Fasting

1 “Shout it aloud, do not hold back.
   Raise your voice like a trumpet.
Declare to my people their rebellion
   and to the descendants of Jacob their sins.

2 For day after day they seek me out;
   they seem eager to know my ways,
as if they were a nation that does what is right
   and has not forsaken the commands of its God.
They ask me for just decisions
   and seem eager for God to come near them.

3 ‘Why have we fasted,’ they say,
   ‘and you have not seen it?
Why have we humbled ourselves,
   and you have not noticed?’

   “Yet on the day of your fasting, you do as you please
   and exploit all your workers.

4 Your fasting ends in quarreling and strife,
   and in striking each other with wicked fists.
You cannot fast as you do today
   and expect your voice to be heard on high.

5 Is this the kind of fast I have chosen,
   only a day for people to humble themselves?
Is it only for bowing one’s head like a reed
   and for lying in sackcloth and ashes?
Is that what you call a fast,
   a day acceptable to the LORD?

    6 “Is not this the kind of fasting I have chosen:
to loose the chains of injustice
   and untie the cords of the yoke,
to set the oppressed free
   and break every yoke?

7 Is it not to share your food with the hungry
   and to provide the poor wanderer with shelter—
when you see the naked, to clothe them,
   and not to turn away from your own flesh and blood?

8 Then your light will break forth like the dawn,
   and your healing will quickly appear;
then your righteousness Or your righteous One will go before you,
   and the glory of the LORD will be your rear guard.

9 Then you will call, and the LORD will answer;
   you will cry for help, and he will say: Here am I.

   “If you do away with the yoke of oppression,
   with the pointing finger and malicious talk,

10 and if you spend yourselves in behalf of the hungry
   and satisfy the needs of the oppressed,
then your light will rise in the darkness,
   and your night will become like the noonday.

11 The LORD will guide you always;
   he will satisfy your needs in a sun-scorched land
   and will strengthen your frame.
You will be like a well-watered garden,
   like a spring whose waters never fail.

12 Your people will rebuild the ancient ruins
   and will raise up the age-old foundations;
you will be called Repairer of Broken Walls,
   Restorer of Streets with Dwellings.

    13 “If you keep your feet from breaking the Sabbath
   and from doing as you please on my holy day,
if you call the Sabbath a delight
   and the LORD’s holy day honorable,
and if you honor it by not going your own way
   and not doing as you please or speaking idle words,

14 then you will find your joy in the LORD,
   and I will cause you to ride in triumph on the heights of the land
   and to feast on the inheritance of your father Jacob.” For the mouth of the LORD has spoken.


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.
