Psalms 19:12
Ver. 12. Who can understand [his] errors?.... Sin is an error, a wandering out of the way of God, swerving from the rule of his word; and many mistakes are made by the people of God themselves; even so many that they cannot number them; they are more than the hairs of their head; they cannot understand, find out and express, neither their number, nor their evil nature, nor the many aggravating circumstances which attend them: this the psalmist said, upon a view of the large extent, glory, and excellency of the word of God; and upon comparing himself with it, in which, as in a glass, he saw how far short he came of it, and what a disagreement and want of conformity there was in him unto it; see Ps 119:97; and he suggests, that though the word he had been describing was perfect, pure, and clean, he was not; nor could he expect any reward of debt, but merely of grace, for his observance of it; and that it was best, under a sense of sin, to have recourse, not to works of righteousness done by men; but to the grace and mercy of God in Christ, as follows:
cleanse thou me from secret [faults]; by which are meant not such sins as are done in secret, and are unknown to men; such as David's sin with Bathsheba, 2Sa 12:12; nor the inward motions of sin in the heart, to which none are privy but God, and a man's own soul; not but that each of these may be properly enough included in such a petition; but sins, which are unknown to a man himself are meant: there are some actions, which, though known when committed, are not known to be sinful ones; and there are some sins which are committed unadvisedly, and through carelessness, and pass unobserved; not only many vain and sinful thoughts pass to and fro uncontrolled, without being taken notice of; but many foolish and idle words are spoken, and many evil actions, through infirmity and inadvertency, are done, which, when a good man, at the close of a day, comes to reflect upon the things that have passed in it, are quite hidden from him, are unknown to him, being unobserved by him; wherefore such a petition is highly proper to be inserted in his address at the throne of grace: and which also supposes the person sensible of the defiling nature of sin, and of his own impotency to cleanse himself from it; and that God only can do it, who does it by the application of the blood of his Son, which cleanses from all sin; for this respects not regenerating and sanctifying grace, but pardoning grace; a manifestation of it, a view of acquittance from sin by Christ, and of freedom from obligation to punishment for it. Psalms 19:13Ver. 13. Keep back thy servant also from presumptuous [sins],.... Some understand these words of persons: the Septuagint, and the versions that follow that, render it "from strangers": such who are strangers to God and godliness; that is, keep from all conversation with them in things sinful, or from others' sins; from having a fellowship with them, being a partaker of them, lest their plagues and punishments should be shared in: others, as the Targum, "from proud men", who are haughty, insolent, and conceited of themselves; lest he should be so corrupted and drawn aside by them: but rather the words are to be understood of sins wilfully, contumaciously, and presumptuously committed; and the petition supposes, that these may be committed by good men, if left to themselves; and that there is a proneness in them to them; and that they would rush into them, were they not kept back and restrained by the powerful and efficacious grace of God: and it also supposes that the saints cannot keep themselves; that God only can keep them from evil; and therefore they pray to him that he would, who does keep them by his power, at least from a final and total falling awaylet them not have dominion over me: neither presumptuous sins, nor any other, Ps 119:133; as they shall not, Ro 6:14; as sin has over wicked men; and they yield a ready obedience to the laws and lusts of it; it reigns over them as a king and tyrant, even unto death: it is something very powerful in good men; it prevails over them, and carries them captive; wherefore they pray it may not have a continued dominion, as it shall not; because they are in another kingdom, and under grace as a governing principle, which reigns through righteousness unto eternal life;then shall I be upright; in heart, and walk uprightly in conversation; being cleansed from secret faults, and kept from notorious crimes, and gross enormities; and shall exercise a conscience void of offence, both to God and man; and be "perfect", as the word is sometimes rendered, at least comparatively; and absolutely so, as washed in Christ's blood, and justified by his righteousness;and I shall be innocent from the great transgression; which some understand of pride, others of apostasy; perhaps the sin against the Holy Ghost may be intended; though the words may be rendered, "from much transgression" {k}; and the sense is, that he should be cleared and acquitted of a multitude of transgressions he had been guilty of; or be preserved from much sin, which otherwise he should have fallen into.{k} br "multa", Montanus, Rivetus, Gejerus, Cocceius; so Ainsworth. Psalms 19:14Ver. 14. Let the words of my mouth,.... Meaning either his speech in common conversation, which should not be filthy and foolish, rotten and corrupt; but such as ministers grace to the hearer: or else his address to God, both in prayer and thanksgiving;and the meditation of my heart; his inward thoughts continually revolving in his mind; or his meditation on the word of God and divine things; or mental prayer, which is not expressed, only conceived in the mind;be acceptable in thy sight; as words and thoughts are, when they are according to the word of God; and as the sacrifices of prayer, whether vocal or mental, and of praise, are through Jesus Christ our Lord. The psalmist, in order to strengthen his faith in God, that he should be heard and answered in the petitions he put up, makes use of the following epithets:O Lord, my strength, or "rock" {l},and my Redeemer; who had been the strength of his life and of his salvation, the rock on which he was built and established, and the Redeemer who had redeemed his life from destruction, and out of the hands of all his enemies, and from all his iniquities.{l} yrwu "rupes mea", Musculus, Junius & Tremellius, Piscator, Cocceius; "mea petra", Pagninus, Montanus, Rivetus; so Ainsworth.
