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."
