Ver. 2 is difficult principally because the reference of the initial "So" is doubtful. By some it is connected with the first clause of ver. 1: "So"--_i.e._, as my God--"have I seen Thee." Others suppose a comparison to be made between the longing just expressed and former ones, and the sense to be, "With the same eager desire as now I feel in the desert have I gazed in the sanctuary." This seems the better view. Hupfeld proposes to transpose the two clauses, as the A.V. has done in its rendering, and thus gets a smoother run of thought. The immediate object of the psalmist's desire is thus declared to be "to behold Thy power and glory," and the "So" is substantially equivalent to "According as." If we retain the textual order of the clauses, and understand the first as paralleling the psalmist's desert longing with that which he felt in the sanctuary, the second clause will state the aim of the ardent gaze--namely, to "behold Thy power and Thy glory." These attributes were peculiarly manifested amid the imposing sanctities where the light of the Shechinah, which was especially designated as "the Glory," shone above the ark.
The first clause of ver. 3 is closely connected with the preceding, and gives the reason for some part of the emotion there expressed, as the introductory "For" shows. But it is a question to which part of the foregoing verses it refers. It is probably best taken as assigning the reason for their main subject--namely, the psalmist's thirst after God. "Where your treasure is, there will your heart be also." Our desires are shaped by our judgments of what is good. The conviction of God's transcendent excellence and absolute sufficiency for all our cravings must precede the direction of these to Him. Unless all enjoyments and possessions, which become ours through our corporeal life, and that life itself, are steadfastly discerned to be but a feather's weight in comparison with the pure gold of God's loving-kindness, we shall not long for it more than for them.
The deep desires of this psalmist were occasioned by his seclusion from outward forms of worship, which were to him so intimately related to the inward reality, that he felt farther away from God in the wilderness than when he caught glimpses of His face, through the power and glory which he saw visibly manifested in the sanctuary. But in his isolation he learns to equate his desert yearnings with his sanctuary contemplations, and thus glides from longing to fruition. His devotion, nourished by forms, is seen in the psalm in the very act of passing on to independence of form; and so springs break out for him in the desert. His passion of yearning after God rebukes and shames our faint desires. This man's soul was all on the stretch to grasp and hold God. His very physical frame was affected by his intense longing. If he did not long too much, most men, even those who thirst after God most, long terribly too little. Strong desire has a joy in its very aching; feeble desire only makes men restless and uncomfortable. Nothing can be more preposterous than tepid aspirations after the greatest and only good. To hold as creed that God's loving-kindness is better than life, and to wish a little to possess it, is surely irrational, if anything is so.
The remaining clauses of ver. 3 and ver. 4 form a transition to the full consciousness of satisfaction which animates the psalmist in the second part. The resolve to praise, and the assurance that he will have occasion to praise, succeed his longing with startling swiftness. The "So" of ver. 4 seems to be equivalent to "Accordingly"--_i.e._, since Thy loving-kindness is such supreme good, and is mine because I have desired it. Continual praise and as continual invocation are the fitting employments of those who receive it, and by these alone can their possession of the loving-kindness bestowed be made permanent. If empty palms are not ever lifted towards God, His gifts will not descend. When these are received, they will fall like morning sunbeams on stony and dumb lips, which before were only parted to let out sighs, and will draw forth music of praise. There are longings which never are satisfied; but God lets no soul that thirsts for Him perish for lack of the water of life. Wisdom bids us fix our desires on that Sovereign Good, to long for which is ennobling and blessed, and to possess which is rest and the beginning of heaven.
