Matthew Poole's Concise Commentary
Psalms 19:7
The law of the Lord, i.e. the doctrine delivered by God to his church, whether by Moses or by other prophets, and holy men of God after him; for the title of law is given not only to the ten commandments, or the moral law, as it is Romans 2:23,25,27 3:31, but also to the whole word of God, as Psalms 1:2, Psalms 119:70 &c.; Jeremiah 8:8 Zechariah 2:6; to the Psalms, as 1 Thessalonians 10:34, 1 Thessalonians 15:25, compared with Psalms 82:6, Psalms 35:19; and to the writings of the prophets, 1 Corinthians 14:21, compared with Isaiah 28:11; yea, even to the gospel itself, as Isaiah 2:3, Isaiah 42:4 5:4,7 Ro 3:27 Galatians 2:21. And in this general sense it must be here understood, because the effects here following do not flow from one, but from all the parts of it, precepts, and counsels, and threatenings, and promises, and God's gracious covenant made with man therein revealed. Having discoursed hitherto of the glory of God shining forth in and demonstrated by the visible heavens, and the heavenly bodies, he now proceeds to another demonstration of God's glory, which he compares with and prefers before the former; which he doth partly, to prevent that excessive admiration of the splendour and beauty of the sun and stars, by the contemplation whereof the heathens were brought to adore them, an error which the Israelites were not free from the danger of, Deuteronomy 4:19; partly, to make the Israelites sensible of their singular obligations to God, who, besides that common light and influence of the heavenly bodies, had given them a peculiar and a more necessary and beneficial light; and partly, to awaken and provoke the Gentiles (into whose hands these Psalms might come) to the study and love of God's law, by representing those excellent advantages which they no less than the Jews might obtain by it. Perfect; without fault or defect, fully and completely discovering both the nature and will of God, and the whole duty and business of man, whom and how he is to worship and serve, what he is to believe and practise, and whatsoever is necessary to his present and eternal happiness; wherein there seems to be a secret reflection upon the former and natural discovery of God by his works of creation, as that which is defective and insufficient for the great and glorious ends here following, which although it did declare so much of God's being and nature as left all men without excuse, Romans 1:20, yet did not fully nor clearly manifest the mind and will of God, nor direct and bring men to eternal salvation. Converting, to wit, from the errors of mind and conversation, in which men without this light do generally wander and perish, unto God, from whom all men are naturally revolted. Or, comforting or reviving, as this word is used, Ruth 4:15 Psalms 23:3 Lamentations 1:11,16. Heb. restoring or bringing back the soul, which was drooping and even going out of the body, through grievous troubles of the outward man, and terrors of the mind and conscience. The testimony of the Lord, i.e. his law, so called because it is a witness between God and man, what God requires of man, and what upon the performance of tllat condition he will do for man. Is sure, Heb. faithful or true, which is most excellent, and proper, and necessary in a witness\'b7 It will not mislead or deceive any man that trusteth to it or followeth it; but will certainly and infallibly bring him to happiness. Making wise unto salvation, as is expressed, 2 Timothy 3:15; which is the only true wisdom. The simple: this is added either,
1. By way of commendation, or as a qualification of the person whom God's word will make wise; he must be humble, and foolish, and little in his own eyes, and willing to be taught: see Matthew 11:25 1 Corinthians 1:25, &c. For God resisteth the proud and scornful, and will not give this wisdom to them. Or rather,
2. By way of contempt, which seems most agreeable both to the use of the words, Proverbs 1:4, Proverbs 9:6 14:15 22:3, and to the scope of the place, which is to set forth the excellency and efficacy of God's law in the general, without any restriction to this or that sort of men. So it may note the weak and foolish, even persons of the lowest capacities, and such as are apt to mistake and are easily seduced, as the word implies\'b7 And yet these, if they will hearken to the instructions of God's word, shall become wise, when those who profess themselves wise shall, by leaning to their own understanding, and despising or neglecting the directions of God's word, become and prove themselves to be fools, Romans 1:22. But this is not spoken exclusively, as if no men of better abilities were thus made wise; but by way of amplification, to show the usefulness of God's word to men of all sorts and sizes.
