That thou mightest be justified.—Strictly, in order that, here as in the Hebrew of the Psalm. Good is, in some way inscrutable to us, educed out of evil, and this is clearly foreseen by God, and forms part of His design, though so as not to interfere with the free-will of man. Religion assumes that the two things, free-will and omnipotence, are reconcilable, though how they are to be reconciled seems an insoluble problem. The same difficulty attaches to every system but one of blank fatalism and atheism. But the theory of fatalism if logically carried out would simply destroy human society.

Psalms 51, in which the quotation occurs, is commonly (in accordance with the heading), though perhaps wrongly, ascribed to David after his sin with Bathsheba. The effect of this sin is to throw out into the strongest relief the justice of the sentence by which it is followed and punished. The original is, “That thou mightest be just in thy speaking; that thou mightest be pure in thy judging.” St. Paul adopts the rendering of the LXX., who make the last word passive instead of active, thus making it apply, not to the sentence given by God, but to the imaginary trial to which by a figure of speech that sentence itself is supposed to be submitted.

Let God be true - Let God be esteemed true and faithful, whatever consequence may follow. This was a first principle, and should be now, that God should be believed to be a God of truth, whatever consequence it might involve. How happy would it be, if all people would regard this as a fixed principle, a matter not to be questioned in their hearts, or debated about, that God is true to his word! How much doubt and anxiety would it save professing Christians; and how much error would it save among sinners! Amidst all the agitations of the world, all conflicts, debates, and trials, it would be a fixed position where every man might find rest, and which would do more than all other things to allay the tempests and smooth the agitated waves of human life.

But every man a liar - Though every man and every other opinion should be found to be false. Of course this included the apostle and his reasoning; and the expression is one of those which show his magnanimity and greatness of soul. It implies that every opinion which he and all others held; every doctrine which had been defended; should be at once abandoned, if it implied that God was false. It was to be assumed as a first principle in all religion and all reasoning, that if a doctrine implied that God was not faithful, it was of course a false doctrine. This showed his firm conviction that the doctrine which he advanced was strictly in accordance with the veracity of the divine promise. What a noble principle is this! How strikingly illustrative of the humility of true piety, and of the confidence which true piety places in God above all the deductions of human reason! And if all people were willing to sacrifice their opinions when they appeared to impinge on the veracity of God; if they started back with instinctive shuddering at the very supposition of such a lack of fidelity in him; how soon would it put an end to the boastings of error, to the pride of philosophy, to lofty dictation in religion! No man with this feeling could be for a moment a universalist; and none could be an infidel.

As it is written - Psalm 51:4. To confirm the sentiment which he had just advanced and to show that it accorded with the spirit of religion as expressed in the Jewish writings, the apostle appeals to the language of David, uttered in a state of deep penitence for past transgressions. Of all quotations ever made, this is one of the most beautiful and most happy. David was overwhelmed with grief; he saw his crime to be awful; he feared the displeasure of God, and trembled before him. Yet "he held it as a fixed, indisputable principle that" God was right. This he never once thought of calling in question. He had sinned against God, God only; and he did not once think of calling in question the fact that God was just altogether in reproving him for his sin, and in pronouncing against him the sentence of condemnation.

That thou mightest be justified - That thou mightest be regarded as just or right, or, that it may appear that God is not unjust. This does not mean that David had sinned against God for the purpose of justifying him, but that he now clearly saw that his sin had been so directly against him, and so aggravated, that God was right in his sentence of condemnation.

In thy sayings - In what thou hast spoken; that is, in thy sentence of condemnation; in thy words in relation to this offence. It may help us to understand this, to remember that the psalm was written immediately after Nathan, at the command of God, had gone to reprove David for his crime; (see the title of the psalm.) God, by the mouth of Nathan, had expressly condemned David for his crime. To this expression of condemnation David doubtless refers by the expression "in thy sayings;" see 2 Samuel 12:7-13.

And mightest overcome - In the Hebrew, "mightest be pure," or mightest be esteemed pure, or just. The word which the Septuagint and the apostle have used, "mightest overcome," is sometimes used with reference to litigations or trials in a court of justice. He that was accused and acquitted, or who was adjudged to be innocent, might be said to overcome, or to gain the cause. The expression is thus used here. As if there were a trial between David and God, God would overcome; that is, would be esteemed pure and righteous in his sentence condemning the crime of David.

When thou art judged - The Hebrew is, "when thou judgest;" that is, in thy judgment pronounced on this crime. The Greek may also be in the middle voice as well as the passive, and may correspond, therefore, in meaning precisely with the Hebrew. So the Arabic renders it. The Syriac renders it, "when they (that is, people) shall judge thee." The meaning, as expressed by David, is, that God is to be esteemed right and just in condemning people for their sins, and that a true penitent, that is, a man placed in the best circumstances to form a proper estimate of God, will see this, though it should condemn himself. The meaning of the expression in the connection in which Paul uses it, is, that it is to be held as a fixed, unwavering principle, that God is right and true, whatever consequences it may involve; whatever doctrine it may overthrow; or whatever man it may prove to be a liar.

yea, let God be—held

true, and every man a liar—that is, even though it should follow from this that every man is a liar.

when thou art judged—so in Ps 51:4, according to the Septuagint; but in the Hebrew and in our version, "when thou judgest." The general sentiment, however, is the same in both—that we are to vindicate the righteousness of God, at whatever expense to ourselves.

as it is written, Psalm 51:4;

that thou mightest be justified in thy sayings, and mightest overcome when thou art judged. This is a proof that God is true, and stands to his word, though men are fallacious, inconstant, and wicked. God made a promise to David, that of the fruit of his body he would set upon his throne; that the Messiah should spring from him; that he would of his seed raise up unto Israel a Saviour. Now David sinned greatly in the case of Bathsheba, 2 Samuel 11:3 (title), but his sin did not make of no effect the truth and faithfulness of God: though David showed himself to be a weak sinful man, yet God appeared true and faithful to every word of promise which he had sworn in truth to him; and therefore when he was brought to a sense of his evil, and at the same time to observe the invariable truth and faithfulness of God, said, "I acknowledge my transgression, &c. against thee, thee only have I sinned and done this evil in thy sight", Psalm 51:3, which confession of sin I make, "that thou mightest be justified in thy sayings"; or "when thou speakest", Psalm 51:4, which is all one; that is, that thou mightest appear to be just, and faithful, and true in all thy promises, in every word that is gone out of thy mouth, which shall not be recalled and made void, on account of my sins; for though I have sinned, thou abidest faithful; and this also I declare with shame to myself, and with adoring views of thine unchangeable truth and goodness: "that thou mightest overcome"; that is, put to silence all such cavils and charges, as if the faith of God could be made void by the unfaithfulness of men: "when thou art judged"; when men will be so bold and daring to arraign thy truth and faithfulness, and contend with thee about them. This now is brought as a full proof, and is a full proof of this truth, that God is always true to his word, though men fail in theirs, and fall into sin. God kept his word with David concerning the stability of his kingdom, his successor, and the Messiah that should spring from him, though he acted a bad part against God. There is some little difference between these words as they stand in the Hebrew text of Psalm 51:4; and as they are cited and rendered by the apostle, in the last clause of them; in the former it is, "that thou mightest be clear"; in the latter, "that thou mightest overcome". Now to vindicate the apostle's version, let it be observed, that the Hebrew word signifies to "overcome", as well as to "be clear"; of which instances may be given out of the Jewish writings. Says (l) Rabba; concerning an argument used by R. Chanina, in a controversy with other Rabbins, by this R. Chanina ben Antigonus, "hath overcome" them: and in another place (m), whosoever "overcomes" a king, they cast him into an empty ditch; where the gloss upon it is, he that overcomes a king by words, that is, by disputing with him, which is a disgrace to a king. So the word is used in the Syriac language in John 16:33. Moreover, the sense is the same, be it rendered either way; for as a man, when he overcomes his adversary, and carries his point against him, is clear of his charges and cavils, so God, when he overcomes in judgment, is clear of the imputations of wicked men. Another difference in the citation is, that what in the psalm is rendered "when thou judgest", is by the apostle, "when thou art judged", Psalm 51:4, the word, which is used by the Psalmist, may be rendered either way; either "when thou judgest", as a word of the same form is rendered, when "thou speakest", in Psalm 51:4; or "when anyone judges of thee", or "when thou art judged": a like instance is in Psalm 46:2; and so it is rendered by the Septuagint, and followed by the apostle, though the word he uses may be considered in the middle voice, and may have an active signification in it; and the phrase, , may be rendered, "when thou judgest", and then both agree.
