The one desire of such a suppliant is for restoration of interrupted access to God. The psalmist embodies that yearning in its more outward form, but not without penetrating to the inner reality in both the parallel petitions which follow. In the first of these, (ver. 2 _b_) the thought is fuller than the condensed expression of it. "Lead me on" or in, says he, meaning, Lead me _to_ and set me _on_. His imagination sees towering above him a great cliff, on which, if he could be planted, he might defy pursuit or assault. But he is distant from it, and the inaccessibility which, were he in its clefts, would be his safety, is now his despair. Therefore he turns to God and asks Him to bear him up in His hands, that he may set his foot on that rock. The figure has been, strangely enough, interpreted to mean a rock of difficulty, but against the usage in the Psalter. But we do not reach the whole significance of the figure if we give it the mere general meaning of a place of safety. While it would be too much to say that "rock" is here an epithet of God (the absence of the definite article and other considerations are against that), it may be affirmed that the psalmist, like all devout men, knew that his only place of safety was in God. "_A_ rock" will not afford adequate shelter; our perils and storms need "_the_ Rock." And, therefore, this singer bases his prayer on his past experience of the safe hiding that he had found in God. Place of refuge and strong tower are distinctly parallel with "rock." The whole, then, is like the prayer in Psalm xxxi. 2, 3: "Be Thou to me a strong rock. For Thou art my rock."
The second pair of verses, containing petition and its ground in past experience (vv. 4, 5), brings out still more clearly the psalmist's longing for the sanctuary. The futures in ver. 4 may be taken either as simple expressions of certainty, or, more probably, as precative, as is suggested by the parallelism with the preceding pair. The "tent" of God is the sanctuary, possibly so called because at the date of the psalm "the ark of God dwelt in curtains." The "hiding-place of Thy wings" may then be an allusion to the Shechinah and outspread pinions of the Cherubim. But the inner reality is more to the psalmist than the external symbols, however his faith was trained to connect the two more indissolubly than is legitimate for us. His longing was no superstitious wish to be near that sanctuary, as if external presence brought blessing, but a reasonable longing, grounded on the fact for his stage of revelation, that such presence was the condition of fullest realisation of spiritual communion, and of the safety and blessedness thence received. His prayer is the deepest desire of every soul that has rightly apprehended the facts of life, its own needs and the riches of God. The guests in God's dwelling have guest-rights of provision and protection. Beneath His wings are safety, warmth, and conscious nearness to His heart. The suppliant may feel far off, at the end of the world; but one strong desire has power to traverse all the distance in a moment. "Where the treasure is, there will the heart be also"; and where the heart is, there the man is.
The ground of this second petition is laid in God's past listening to vows, and His having given the psalmist "the heritage of those that fear Thy name." That is most naturally explained as meaning primarily the land of Israel, and as including therein all other blessings needful for life there. While it is capable of being otherwise understood, it is singularly appropriate to the person of David during the period of Absalom's rebellion, when victory was beginning to declare itself for the king. If we suppose that he had already won a battle (2 Sam. xviii. 6), we can understand how he takes that success as an omen and urges it as a plea. The pair of verses will then be one instance of the familiar argument which trustful hearts instinctively use, when they present past and incomplete mercies as reasons for continued gifts, and for the addition of all which is needed to "perfect that which concerneth" them. It rests on the confidence that God is not one who "begins and is not able to finish."
