10 Create in me a clean heart, O God! In the previous part of the psalm David has been praying for pardon. He now requests that the grace of the Spirit, which he had forfeited, or deserved to have forfeited, might be restored to him. The two requests are quite distinct, though sometimes confounded together, even by men of learning. He passes from the subject of the gratuitous remission of sin to that of sanctification. And to this he was naturally led with earnest anxiety, by the consciousness of his having merited the loss of all the gifts of the Spirit, and of his having actually, in a great measure, lost them. By employing the term create, he expresses his persuasion that nothing less than a miracle could effect his reformation, and emphatically declares that repentance is the gift of God. The Sophists grant the necessity of the aids of the Spirit, and allow that assisting grace must both go before and come after; but by assigning a middle place to the free will of man, they rob God of a great part of his glory. David, by the word which he here uses, describes the work of God in renewing the heart in a manner suitable to its extraordinary nature, representing it as the formation of a new creature.

As he had already been endued with the Spirit, he prays in the latter part of the verse that God would renew a right spirit within him But by the term create, which he had previously employed, he acknowledges that we are indebted entirely to the grace of God, both for our first regeneration, and, in the event of our falling, for subsequent restoration. He does not merely assert that his heart and spirit were weak, requiring divine assistance, but that they must remain destitute of all purity and rectitude till these be communicated from above. By this it appears that our nature is entirely corrupt: for were it possessed of any rectitude or purity, David would not, as in this verse, have called the one a gift of the Spirit, and the other a creation.

In the verse which follows, he presents the same petition, in language which implies the connection of pardon with the enjoyment of the leading of the Holy Spirit. If God reconcile us gratuitously to himself, it follows that he will guide us by the Spirit of adoption. It is only such as he loves, and has numbered among his own children, that he blesses with a share of his Spirit; and David shows that he was sensible of this when he prays for the continuance of the grace of adoption as indispensable to the continued possession of the Spirit. The words of this verse imply that the Spirit had not altogether been taken away from him, however much his gifts had been temporarily obscured. Indeed, it is evident that he could not be altogether divested of his former excellencies, for he seems to have discharged his duties as a king with credit, to have conscientiously observed the ordinances of religion, and to have regulated his conduct by the divine law. Upon one point he had fallen into a deadly lethargy, but he was not given over to a reprobate mind;” and it is scarcely conceivable that the rebuke of Nathan the prophet should have operated so easily and so suddenly in arousing him, had there been no latent spark of godliness still remaining in his soul. He prays, it is true, that his spirit may be renewed, but this must be understood with a limitation. The truth on which we are now insisting is an important one, as many learned men have been inconsiderately drawn into the opinion that the elect, by falling into mortal sin, may lose the Spirit altogether, and be alienated from God. The contrary is clearly declared by Peter, who tells us that the word by which we are born again is an incorruptible seed, (1 Peter 1:23;) and John is equally explicit in informing us that the elect are preserved from falling away altogether, (1 John 3:9.) However much they may appear for a time to have been cast off by God, it is afterwards seen that grace must have been alive in their breast, even during that interval when it seemed to be extinct. Nor is there any force in the objection that David speaks as if he feared that he might be deprived of the Spirit. It is natural that the saints, when they have fallen into sin, and have thus done what they could to expel the grace of God, should feel an anxiety upon this point; but it is their duty to hold fast the truth that grace is the incorruptible seed of God, which never can perish in any heart where it has been deposited. This is the spirit displayed by David. Reflecting upon his offense, he is agitated with fears, and yet rests in the persuasion that, being a child of God, he would not be deprived of what indeed he had justly forfeited.

12 Restore unto me the joy of thy salvation He cannot dismiss his grief of mind until he have obtained peace with God. This he declares once and again, for David had no sympathy with those who can indulge themselves in ease when they are lying under the divine displeasure. In the latter clause of the verse, he prays as in the verses preceding, that the Holy Spirit might not be taken away from him. There is a slight ambiguity in the words. Some take תסמכני, thismecheni, to be the third person of the verb, because רוח, ruach, is feminine, and translate, let the Spirit uphold me. The difference is immaterial, and does not affect the meaning of the passage. There is more difficulty in fixing the sense of the epithet נדיבה, nedibah, which I have translated free As the verb נדב, nadab, signifies to deal liberally, princes are in the Hebrew called, by way of eminence, נדיבים, nedibim, which has led several learned men to think that David speaks here of a princely or royal spirit; and the translators of the Septuagint rendered it accordingly ἡγεμονικον. The prayer, in this sense, would no doubt be a suitable one for David, who was a king, and required a heroical courage for the execution of his office. But it seems better to adopt the more extensive meaning, and to suppose that David, under a painful consciousness of the bondage to which he had been reduced by a sense of guilt, prays for a free and cheerful spirit. ²⁶⁹²⁶⁹     Some commentators refer the clause, upon which Calvin is here commenting, to the Holy Spirit, and others to the qualities of mind with which David desired to be endued. The translators of our English Bible understand the expression in the first sense, reading, “thy free Spirit.” The word thy is a supplement, but it does not appear to be liable to any material objection. Fry, who adopts the same view, reads, “bountiful or spontaneously flowing Spirit;” and observes, that the word נדיבה, nedibah, “is more still than spontaneously flowing: it signifies to flow both spontaneously and plentifully: ‘prae uberitate succi sponte fluens.’ This epithet of the indwelling Spirit will be best explained from our Lord’s own words, John 4:14, and 7:38.” Others refer the expression to the mind of the Psalmist. Mudge reads, “And let a plentiful effusion of spirit support me.” Dimock, “Let a free spirit sustain me;” “that is,” says he, “let me not be enslaved, as I have been, by my sinful passions.” Green, “And support with a cheerful spirit.” French and Skinner, “And may a willing spirit uphold me;” by which they understand, “a spirit devoted to the service of God.” Walford, following the Septuagint, reads, “And with a princely spirit sustain me.” “David,” says this critic, “was so overwhelmed by the consciousness of his extreme iniquity, so broken in spirit, courage, and fortitude, as to feel altogether incompetent to the discharge of his office, as the King of Israel. He therefore addresses this petition to God, in the hope that he would grant to him a renewal of that powerful energy by which he had at first been fitted for an employment so every way unsuitable to his lowly descent, and his employment as a shepherd.” This invaluable attainment, he was sensible, could only be recovered through divine grace.
