The swift transitions of feeling in this psalm may seem strange to colder natures whose lives run smoothly, but reveal a brother-soul to those who have known what it is to ride on the top of the wave and then to go down into its trough. What is peculiar to the psalm is not only the inclusion of the whole gamut of feeling, but the force with which each key is struck and the persistence through all of the one ground tone of cleaving to Jehovah. The poetic temperament passes quickly from hope to fear. The devout man in sorrow can sometimes look away from a darkened earth to a bright sky, but the stern realities of pain and loss again force themselves in upon him. The psalm is like an April day, in which sunshine and rain chase each other across the plain. "The beautiful uncertain weather, Where gloom and glory meet together," makes the landscape live, and is the precursor of fruitfulness. The stream of the psalmist's thoughts now runs in shadow of grim cliffs and vexed by opposing rocks, and now opens out in sunny stretches of smoothness; but its source is "In Thee, Jehovah, do I take refuge" (ver. 1): and its end is "Be strong, and let your heart take courage, all ye that wait for Jehovah" (ver. 24). The first turn of the stream is in vv. 1-4, which consist of petitions and their grounds. The prayers reveal the suppliant's state. They are the familiar cries of an afflicted soul common to many psalms, and presenting no special features. The needs of the human heart are uniform, and the cry of distress is much alike on all lips. This sufferer asks, as his fellows have done and will do, for deliverance, a swift answer, shelter and defence, guidance and leading, escape from the net spread for him. These are the commonplaces of prayer, which God is not wearied of hearing, and which fit us all. The last place to look for originality is in the "sighing of such as be sorrowful." The pleas on which the petitions rest are also familiar. The man who trusts in Jehovah has a right to expect that his trust will not be put to shame, since God is faithful. Therefore the first plea is the psalmist's faith, expressed in ver. 1 by the word which literally means to flee to a refuge. The fact that he has done so makes his deliverance a work of God's "righteousness." The metaphor latent in "flee for refuge" comes into full sight in that beautiful plea in ver. 3, which unsympathetic critics would call illogical, "_Be_ for me a refuge-rock, for ... Thou _art_ my rock." Be what Thou art; manifest Thyself in act to be what Thou art in nature: be what I, Thy poor servant, have taken Thee to be. My heart has clasped Thy revelation of Thyself and fled to this strong tower. Let me not be deceived and find it incapable of sheltering me from my foes. "Therefore for Thy name's sake," or because of that revelation and for its glory as true in men's sight, deliver me. God's nature as revealed is the strongest plea with Him, and surely that
