This psalm purports to be a psalm of David; and there is nothing in the psalm that is contrary to this supposition. Why it has its place among the psalms which are designated as the compositions of “the sons of Korah,” and had not its place among those which are ascribed to David Ps. 1–70 we have no means of ascertaining. It is not said, however, that those were the only psalms of David, and there is no improbability in supposing that he may have composed others. It is not improperly named “a prayer,” since it is made up mostly of petitions, though this is true of others which are called “psalms,” and though it is true that this one has so much of praise in it that it might also (as it is in the margin) be designated a psalm. The occasion on which it was composed is unknown, but it has been commonly supposed that it was written in the time of the persecutions under Saul. DeWette regards it as a national song composed in a time of national trouble.
This psalm does not admit of any minute subdivision. It is made up of earnest prayers, with reasons why those prayers should be answered; and perhaps the leading practical suggestion which would properly follow from the psalm is, that it is proper for us, in our prayers, to urge reasons why they should be answered: the reasons why we pray at all. We cannot, indeed, suppose that we can suggest anything which would not occur to the divine mind, but in all our prayers there is some reason why we pray; there are reasons why we ask the particular things which are the burden of our supplications, and it cannot be improper, in order that our own minds at least may be suitably impressed, to mention those reasons when we come before God.
