Here is, 1. David's appeal to God concerning his love to his precepts: "Lord, thou knowest all things, thou knowest that I love them; consider it then, and deal with me as thou usest to deal with those that love thy word, which thou hast magnified above all thy name." He does not say, "Consider how I fulfil thy precepts;" he was conscious to himself that in many things he came short; but, "Consider how I love them." Our obedience is pleasing to God, and pleasant to ourselves, only when it comes from a principle of love. 2. His petition thereupon: "Quicken me, to do my duty with vigour; revive me, keep me alive, not according to any merit of mine, though I love thy word, but according to thy lovingkindness;" to that we owe our lives, nay, that is better than live itself. We need not desire to be quickened any further than God's lovingkindness will quicken us.

Seven times a day do I praise thee,.... That is, very often in a day; not a day passed over his head but he praised the Lord, and often in the day; so the phrase "seven times" is used, Psa 12:6. Praise is comely for the saints, delightful and well pleasing to God, being offered up in faith and through Christ; and should be frequent, since our mercies, temporal and spiritual, are daily renewed; and therefore we should always, in everything, for everything, and at all seasons, give thanks to God, Eph 5:20, Th1 5:18;

because of thy righteous judgments: either upon his enemies, the persecuting princes, as Aben Ezra; so saints may and should, and will praise the Lord, for his righteous judgments on the enemies of his church and people, because not only of their deliverance from them, but because of the honour of his justice, and the glory of his name; see Rev 18:20; or because of the word of God, the precepts, ordinances, and doctrines of it, which are all righteous; for his knowledge of them, and for the benefit and comfort received from them; see Psa 119:7.
