I will praise thee He affirms it to be a singular instance of the loving-kindness of God, if a person has made considerable proficiency in his law. As a token and testimony of this, he here puts the giving of thanks to God; as if he should say, Lord, thou wilt confer upon me an inestimable blessing, if thou instruct me in thy law. It follows, therefore, that nothing in this life is more to be desired than this; and my fervent prayer is, that we may be fairly and fully convinced of the truth of it. For while searching carefully after such things as we deem advantageous to us, we do not overlook any earthly convenience, and yet we neglect that which is of most importance. The phrase, the judgments of thy righteousness, is the same with the commandments, in which perfect righteousness is comprehended; and thus the prophet commends God's law on account of the thorough perfection of the doctrine contained in it. From this verse we learn, that none will praise God unfeignedly and cordially but he who has made such proficiency in his school as to mold his life into subjection to him. It is vain to make a pretense of praising God with the mouth and the tongue if we dishonor him by our life. Hence the prophet very justly here makes the fruit of genuine piety to consist in celebrating the praises of God without hypocrisy.

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.

I will praise thee with uprightness of (d) heart, when I shall have learned thy righteous (e) judgments.
(d) For true religion stands in serving God without hypocrisy.
(e) That is, your precepts, which contain perfect righteousness.

I 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.
(o) "judicia justitiae tuae", Pagninus, Montanus, Tigurine version, Musculus, Gejerus; so Junius & Tremellius, Piscator, Michaelis.

judgments--rules of conduct formed by God's judicial decisions; hence the wide sense of the word in the Psalm, so that it includes decisions of approval as well as condemnation.

When - When by thy good spirit I shall he more fitly instructed in the meaning of thy word.
