David, in this psalm, is full of complaints, yet those did neither jostle out his praises nor put him out of tune for them; whatever condition a child of God is in he does not want matter for praise and therefore should not want a heart. See here, 1. How often David praised God - Seven times a day, that is, very frequently, not only every day, but often every day. Many think that once a week will serve, or once or twice a day, but David would praise God seven times a day at least. Praising God is a duty which we should very much abound in. We must praise God at every meal, praise him upon all occasions, in every thing give thanks. We should praise God seven times a day, for the subject can never be exhausted and our affections should never be tired. See Psa 119:62. 2. What he praised God for - because of thy righteous judgments. We must praise God for his precepts, which are all just and good, for his promises and threatenings and the performance of both in his providence. We are to praise God even for our afflictions, if through grace we get good by them.

TAU.--The Twenty-second and last Part.

TAU. Let my cry come near before thee, O Lord,.... Not "my praise", as the Syriac version; but "my prayer", put up in great distress, and with great vehemence and importunity; see Psa 119:145; and when it is desired it might "come near before" the Lord, it does not so much suppose distance of place between the petitioner and the petitioned as earth is from heaven, as Aben Ezra observes, as distance of state and condition; the petitioner being a creature, and a sinful creature, and whose sins had separated between God and him: and now the only way of access is by Christ; prayer can only pass to God through him, who is the only Mediator between God and man; by whom persons and services are brought near unto, him with acceptance. The sum of this request is, that his prayer might not be rejected and shut out; but that it might be admitted, might come up before God, and into his ears, and be regarded by him, and accepted with him;

give me understanding according to thy word; meaning not natural, but spiritual understanding; not that he was without any, as natural men are, whose understandings are darkened; for he had a large share of understanding of spiritual things; but he wanted more, he desired to know more of himself, of his wants and weaknesses; to know more of God in Christ, and of Christ, his person, offices, and grace; to know more of the doctrines of the word, and of the duties of religion; and particularly that he might have a better understanding of the business of prayer, and might know both what to pray for, and how to pray as he ought; all which is a gift from God: and he desires in all to be directed "according to the word" of God, the means of enlightening the understanding, and of increasing spiritual knowledge; or else he means the promise of God, that he would give him more knowledge and understanding; that he might be taught of God, and follow on to know him, and increase in every branch of spiritual knowledge.
