| Barnes' Notes on the Bible I will praise thee with uprightness of heart - With an upright and sincere heart. When I shall have learned - Hebrew, "In my learning." In the practice or act of learning them. His own experience of their nature, influence, and value would lead him to sincere praise. He had no doubt of finding that they were worthy of his praises, and of seeing in them more and more occasion to glorify and honor God. The more we know of God, the more shall we see in him to praise. The larger our acquaintance and experience, the more our hearts will be disposed to magnify his name. This remark must extend to all that there is in God to be learned; and as that is infinite, so there will be occasion for renewed and more elevated praise to all eternity. Thy righteous judgments - Margin, as in Hebrew, "Judgments of thy righteousness." The laws or statutes which God, as a righteous or just God, appoints to be the rule of conduct to his creatures.
Gill's Exposition of the Entire BibleI will praise thee with uprightness of heart,.... In the most sincere manner, in the most affectionate way, with the whole heart; sensible of great favours received, and great obligations laid under; see Psalm 9:1; when I shall have learned thy righteous judgments; or, "the judgments of thy righteousness" (o): of the righteousness of God, declared in his righteous law; which is founded upon, and is according to, the strictest rules of justice and equity; and so are all the precepts of it: and of the righteousness of Christ, revealed in the Gospel; by which God appears to be just, while he is the justifier of him that believes in Jesus. Now the precepts of the one, and the doctrines of the other, are to be learned, and learned of God, in his word and by his Spirit. The psalmist had been learning them, but was desirous of learning more of them, not being a complete proficient in them; and of learning them, not merely in the theory, but in the practice and experience of them; which, when he had attained unto, as he hoped he should, it would be matter of the most sincere praise and thankfulness.

Matthew Henry's Concise Commentary119:1-8 This psalm may be considered as the statement of a believer's experience. As far as our views, desires, and affections agree with what is here expressed, they come from the influences of the Holy Spirit, and no further. The pardoning mercy of God in Christ, is the only source of a sinner's happiness. And those are most happy, who are preserved most free from the defilement of sin, who simply believe God's testimonies, and depend on his promises. If the heart be divided between him and the world, it is evil. But the saints carefully avoid all sin; they are conscious of much evil that clogs them in the ways of God, but not of that wickedness which draws them out of those ways. The tempter would make men think they are at them out of those ways. The tempter would make men think they are at liberty to follow the word of God or not, as they please. But the desire and prayer of a good man agree with the will and command of God. If a man expects by obedience in one thing to purchase indulgence for disobedience in others, his hypocrisy will be detected; if he is not ashamed in this world, everlasting shame will be his portion. The psalmist coveted to learn the laws of God, to give God the glory. And believers see that if God forsakes them, the temper will be too hard for them.
Matthew Henry's Whole Bible CommentaryVerses 7-8 Here is, I. David's endeavour to perfect himself in his religion, and to make himself (as we say) master of his business. He hopes to learn God's righteous judgments. He knew much, but he was still pressing forward and desired to know more, as knowing this, that he had not yet attained; but as far as perfection is attainable in this life he reached towards it, and would not take up short of it. As long as we live we must be scholars in Christ's school, and sit at his feet; but we should aim to be head-scholars, and to get into the highest form. God's judgments are all righteous, and therefore it is desirable not only to learn them, but to be learned in them, mighty in the scriptures. II. The use he would make of his divine learning. He coveted to be learned in the laws of God, not that he might make himself a name and interest among men, or fill his own head with entertaining speculations, but, 1. That he might give God the glory of his learning: I will praise thee when I have learned thy judgments, intimating that he could not learn unless God taught him, and that divine instructions are special blessings, which we have reason to be thankful for. Though Christ keeps a free-school, and teaches without money and without price, yet he expects his scholars should give him thanks both for his word and for his Spirit; surely it is a mercy worth thanks to be taught so gainful a calling as religion is. Those have learned a good lesson who have learned to praise God, for that is the work of angels, the work of heaven. It is an easy thing to praise God in word and tongue; but those only are well learned in this mystery who have learned to praise him with uprightness of heart, that is, are inward with him in praising him, and sincerely aim at his glory in the course of their conversation as well as in the exercises of devotion. God accepts only the praises of the upright. 2. That he might himself come under the government of that learning: When I shall have learned thy righteous judgments I will keep thy statutes. We cannot keep them unless we learn them; but we learn them in vain if we do not keep them. Those have well learned God's statutes who have come up to a full resolution, in the strength of his grace, to keep them. III. His prayer to God not to leave him: "O forsake me not! that is, leave me not to myself, withdraw not thy Spirit and grace from me, for then I shall not keep thy statutes." Good men see themselves undone if God forsakes them; for then the tempter will be too hard for them. "Though thou seem to forsake me, and threaten to forsake me, and dost, for a time, withdraw from me, yet let not the desertion be total and final; for that is hell. O forsake me not utterly! for woe unto me if God departs from me." 2. BETH. |
