The first part of this verse is explained in different ways. Some draw from it this meaning, that the true servants of God are contemptible and worthless in their own estimation. If we adopt this interpretation, the copula and, which David does not express, must be supplied, making the reading thus, He is vile and despised in his own eyes. But besides the consideration, that, if this had been the sense, the words would probably have been joined together by the copula and, I have another reason which leads me to think that David had a different meaning, He compares together two opposite things, namely, to despise perverse and worthless characters, and to honor the righteous and those who fear God. In order that these two clauses may correspond with each other, the only sense in which I can understand what is here said about being despised is this, that the children of God despise the ungodly, and form that low and contemptuous estimate of them which their character deserves. The godly, it is true, although living a praiseworthy and virtuous life, are not inflated with presumption, but, on the contrary, are rather dissatisfied with themselves, because they feel how far short they are as yet of the perfection which is required. When, however, I consider what the scope of the passage demands, I do not think that we are here to view the Psalmist as commending humility or modesty, but rather a free and upright judgment of human character, by which the wicked, on the one hand, are not spared, while virtue, on the other, receives the honor which belongs to it; for flattery, which nourishes vices by covering them, is an evil not less pernicious than it is common. I indeed admit, that if the wicked are in authority, we ought not to carry our contempt of them the length of refusing to obey them in so far as a regard to our duty will permit; but, at the same time, we must beware of flattery and of accommodating ourselves to them, which would be to involve us in the same condemnation with them. He who not only seems to regard their wicked actions with indifference, but also honors them, shows that he approves of them as much as it is in his power. Paul therefore teaches us, (Ephesians 5:11,) that it is a species of fellowship with the unfruitful works of darkness when we do not reprove them. It is certainly a very perverse way of acting, when persons, for the sake of obtaining the favor of men, will indirectly mock God; and all are chargeable with doing this who make it their business to please the wicked. David, however, has a respect, not so much to persons as to wicked works. The man who sees the wicked honored, and by the applause of the world rendered more obstinate in their wickedness, and who willingly gives his consent or approbation to this, does he not, by so doing, exalt vice to authority, and invest it with sovereign power? "But woe," says the prophet Isaiah, (Isaiah 5:20,) "unto them that call evil good, and good evil; that put darkness for light, and light for darkness." Nor ought it to be regarded as a rude or violent manner of speaking, when David calls base and wicked persons reprobates, although they may be placed in an exalted and honorable station. If (as Cicero affirms, in his book entitled The Responses of the Aruspices) the inspectors of the entrails of the sacrifices, and other heathen soothsayers, applied to worthless and abandoned characters the term rejected, although they excelled in dignity and riches, why should not a prophet of God be permitted to apply the name of degraded outcasts to all who are rejected by God? The meaning of the Psalmist, to express it in a few words, is, that the children of God freely judge of every man's doings, and that for the purpose of obtaining the favor of men, they will not stoop to vile flattery, and thereby encourage the wicked in their wickedness. What follows immediately after, namely, to honor the righteous and those who fear God, is no mean virtue. As they are often, as it were, the filth and the offscouring of all things in the estimation of the world, so it frequently happens that those who show them favor and sympathy, excite against themselves every where the hatred of the world. The greater part of mankind, therefore, refuse the friendship of good men, and leave them to be despised, which cannot be done without grievous and heinous injury to God. Let us learn then not to value men by their estate or their money, or their transitory honors, but to hold in estimation godliness, or the fear of God. And certainly no man will ever truly apply his mind to the study of godliness who does not, at the same time, reverence the servants of God; as, on the other hand, the love we bear to them incites us to imitate them in sanctity of life. When he hath sworn to his own hurt. The translation of the LXX. would agree very well with the scope of the passage, were it not that the points which are under the words in the Hebrew text will not bear such a sense. [1] It is, indeed, no proof of the inaccuracy of their rendering, that it does not agree with the points; for, although the Jews have always used the points in reading, it is probable that they did not always express them in writing. I, however, prefer following the commonly received reading. And the meaning is, that the faithful will rather submit to suffer loss than break their word. When a man keeps his promises, in as far as he sees it to be for his own advantage, there is in this no argument to prove his uprightness and faithfulness. But when men make a promise to each other, there is nothing more common than from some slight loss which the performance of it would occasion, to endeavor to find a pretext for breaking their engagements. Every one considers with himself what is for his own advantage, and if it puts him to inconvenience or trouble to stand to his promises, he is ingenious enough to imagine that he will incur a far greater loss than there is any reason to apprehend. It seems, indeed, a fair excuse when a man complains that, if he does not depart from his engagement, he will suffer great loss. Hence it is, that we generally see so much unfaithfulness among men, that they do not consider themselves bound to perform the promises which they have made, except in so far as it will promote their own personal interest. David, therefore, condemning this inconstancy, requires the children of God to exhibit the greatest steadfastness in the fulfillment of their promises. Here the question might be asked, If a man, having fallen into the hands of a highwayman, promise him a sum of money to save his life, and if, in consequence of this, he is let go, should he in that case keep his promise? Again, if a man has been basely deceived, in entering into a contract, is it lawful for him to break the oath which he shall have made in such an engagement? With respect to the highwayman, he who confers upon him money falls into another fault, for he supports at his own expense a common enemy of mankind to the detriment of the public welfare. David does not impose upon the faithful such an alternative as this, but only enjoins them to show a greater regard to their promises than to their own personal interests, and to do this especially when their promises have been confirmed by an oath. As to the other case, namely, when a person has sworn, from being deceived and imposed upon by wicked artifice he ought certainly to hold the holy name of God in such veneration, as rather patiently to submit to loss than violate his oath. Yet it is perfectly lawful for him to discover or reveal the fraud which has been practiced upon him, provided he is not led to do so by a regard to his own personal interest; and there is, besides, nothing to hinder him from peaceably endeavoring to compromise the matter with his adversary. Many of the Jewish expositors restrict this passage to vows, as if David exhorted the faithful to perform their vows when they have promised to humble and afflict themselves by fasting. But in this they are mistaken. Nothing is farther from his meaning than this, for he discourses here only of the second table of the law, and of the mutual rectitude which men should maintain in their dealings with one another.

Footnotes

1 - "The LXX., instead of lhr, [lehara,] to hurt, seem to have read lhr, [leharea,] to his fellow, for they render it, to plesion autou, to his neighbor, and so the Syriac, and Latin, and Arabic, and Ethiopic." -- Hammond. This rendering agrees very well with the scope of the Psalm, which relates to our dealing justly with our fellow-men; and it represents the good man as scrupulously performing the promissory oaths which he makes to his neighbor. But the ordinary reading, he sweareth to his own hurt, and changeth not, sets forth the moral integrity of the good man in a still more striking light, by describing him as performing his oath in the face of the greatest temptations to break it, when the performance of it may prove detrimental to his own interests; and this is no mean trial of a man's virtue.

In whose eyes a vile person is contemned - That is, who does not show respect to a man of base or bad character on account of his wealth, his position, or his rank in life. He estimates character as it is in itself, and not as derived from rank, relationship, or station. While, as stated in the previous verse, he is not disposed to take up a false or evil report against another, he is at the same time disposed to do justice to all, and does not honor those who do not deserve to be honored, or apologise for base conduct because it is committed by one of exalted station or rank. Loving virtue and piety for their own sake, he hates all that is opposite; and where conduct deserves reprobation, no matter where found, he does not hesitate to avow his conviction in regard to it. The sentiment here is substantially the same as in Psalm 1:1. See the notes at that verse.
But he honoreth them that fear the Lord - No matter in what rank or condition of life they may be found. Where there is true piety he honors it. He is willing to be known as one that honors it, and is willing to bear all the reproach that may be connected with such a deeply cherished respect, and with such an avowal. Compare Psalm 1:1.
He that sweareth to his own hurt, and changeth not - Who has made a promise, or entered into a contract, that is likely to turn out contrary to his expectations, to his own disadvantage; but who still adheres to his engagement. If the thing itself is wrong; if he has made a promise, or pledged himself to do a wicked thing, he cannot be under obligation to execute it; he should at once abandon it (compare the notes at Matthew 14:9); but he is not at liberty to violate an agreement simply because it will be a loss to him, or because he ascertains that it will not be, as he supposed, to his advantage. The principles here laid down will extend to all contracts or agreements, pecuniary or otherwise, and should be a general principle regulating all our transactions with our fellow-men. The only limitation in the rule is that above stated, when the promise or the contract would involve that which is morally wrong.

In whose eves a vile person is contemned -
7. This man judges of others by their conduct; he tries no man's heart. He knows men only by the fruits they bear; and thus he gains knowledge of the principle from which they proceed. A vile person, נמאס nimas, the reprobate, one abandoned to sin; is despised, נבזה nibzeh, is loathsome, as if he were covered with the elephantiasis or leprosy, for so the word implies. He may be rich, he may be learned, he may be a great man and honorable with his master, in high offices in the state; but if he be a spiritual leper, an infidel, a profligate, the righteous man must despise him, and hold him, because he is an enemy to God and to man, in sovereign contempt. If he be in power, he will not treat him as if worthy of his dignity; while he respects the office he will detest the man. And this is quite right; for the popular odium should ever be pointed against vice.
Aben Ezra gives a curious turn to this clause, which he translates thus: "He is mean and contemptible in his own eyes;" and it is certain that the original, נבזה בעיניו נמאס nibzeh beeynaiv nimas, will bear this translation. His paraphrase on it is beautiful: "A pious man, whatever good he may have done, and however concordant to the Divine law he may have walked, considers all this of no worth, compared with what it was his duty to do for the glory of his Creator." A sentiment very like that of our Lord, Luke 17:10 : "So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants; we have done that which was our duty to do."
Taken in this sense, the words intimate, that the man who is truly pious, who is a proper member of the Church militant, and is going straight to the Church triumphant, is truly humble; he knows he has nothing but what he has received, he has no merit, he trusts not in himself, but in the living God. He renounces his own righteousness, and trusts in the eternal mercy of God through the infinitely meritorious atonement made by Jesus Christ. The language of his heart is: -
"I loathe myself when God I see,And into nothing fall;
Content that thou exalted be,And Christ be all in all."
He honoureth them that fear the Lord -
8. This cause is a proof, however just the sentiment, that Aben Ezra has mistaken the meaning of the preceding clause. The truly pious man, while he has in contempt the honorable and right honorable profligate, yet honors them that fear the Lord, though found in the most abject poverty; though, with Job, on the dunghill, or, with Lazarus, covered with sores at the rich man's gate. Character is the object of his attention; persons and circumstances are of minor importance.
The fear of the Lord is often taken for the whole of religion; and sometimes for that reverence which a man feels for the ma jesty and holiness of God, that induces him to hate and depart from evil. Here it may signify the lowest degree of religion, repentance whereby we forsake sin.
Sweareth to his own hurt, and changeth not -
9. If at any time he have bound himself by a solemn engagement to do so and so, and he finds afterwards that to keep his oath will be greatly to his damage; yet such reverence has he for God and for truth that he will not change, be the consequences what they may. He is faithful also to his promises; his bare word will bind him equally with an oath. He that will not be honest without an oath will not be honest with one.
The Hebrew might be thus translated: "He sweareth to afflict himself, and does not change;" and thus the Chaldee has rendered this clause. He has promised to the Lord to keep his body under, and bring it into subjection; to deny himself that he may not pamper the flesh, and have the more to give to the poor.

(b) In whose eyes a vile person is contemned; but he honoureth them that fear the LORD. [He that] sweareth to [his own] hurt, and changeth not.
(b) He who flatters not the ungodly in their wickedness.

In whose eyes a vile person is contemned,.... A "vile" man is a very wicked, profligate, and abandoned creature, one that is to every good work reprobate; and such sometimes are in high places, Psalm 12:8; and are greatly caressed and esteemed by the men of the world; but then, as they are an abomination to God, they should be despised by his people, let them be what they will as to their riches, honours, and wisdom among men; as Haman was by Mordecai, Esther 3:2; and Ahab by Elisha, 2-Kings 3:14; and such who keep company with, and express a delight and pleasure in such sort of persons, ought by no means to have a place in the house of God. Some understand this of a good man being "despised in his own eyes", as it may be rendered (f); on account of his vileness, and the imperfection of his obedience, and as expressive of his great humility, esteeming others better than himself; and who renounces himself, and is rejected by himself, having a very mean opinion of himself; which is the sense of the Targum, Aben Ezra, and Kimchi; and which is no bad sense, though the former is countenanced by what follows;
but he honoureth them that fear the Lord; who have the covenant grace of fear wrought in their hearts, and serve the Lord with reverence and godly fear; that is, who are truly religious and godly persons; these such who are fit members of the church of Christ love heartily, esteem of highly, and honour them by thinking and speaking well of them, and behaving with great respect and decency to them; see Romans 12:10;
he that sweareth to his own hurt, and changeth not; having taken a solemn oath, so sacred is it with him, and such a regard has he to the name of God, by whom he swears, that though it is to his civil loss and detriment, yet he will not break it and depart from it, but punctually observe it: some render it, "he that swears to his neighbour, and changeth not" (g); he that is just to his word, faithful to his promises, that exactly fulfils all the obligations he lays himself under unto others; he that is honest and upright in all his dealings. The Jewish writers interpret this clause of a man's vowing and swearing to afflict himself by fasting, which, though it is to the emaciating of his body, yet he strictly observes his vow or oath; but this is foreign from the scope of the place: it might be rendered, "he that swears to do evil, and does not recompense or perform" (h), it being better to break through such an oath than to keep it; see Leviticus 5:4.
(f) "qui despicit se in oculis suis", so some in Vatablus; "ille est despectus in propriis oculis, reprobatus", Gussetius, p. 453. (g) , Sept. "proximo suo", V. L. Sic. Syr. Ar. Aethiop. (h) So Ainsworth.

Love and hate are regulated by a regard to God.
sweareth . . . hurt--or what so results (compare Leviticus 5:4).

Vile - An ungodly man. Honoureth - He highly esteems and loves them, though they be mean as to their worldly condition, and though they may differ from him in some opinions or practices of lesser moment. Sweareth - A promissory oath. Hurt - To his own damage. As if a man solemnly swear, that he will sell him such an estate at a price below the full worth; or that, he will give a poor man such a sum of money, which afterwards he finds inconvenient to him. Changeth not - His purpose, but continues firm and resolved to perform his promise.
