The psalmist anticipates that a rebuilt Zion will ensure a worshipping world. He expresses that confidence, which he shares with Isa. xl.-lxvi., in vv. 15-18. The name and glory of Jehovah will become objects of reverence to all the earth, because of the manifestation of them by the rebuilding of Zion, which is a witness to all men of His power and tender regard to His people's cry. The past tenses of vv. 16, 17, do not indicate that the psalm is later than the Restoration. It is contemplated as already accomplished, because it is the occasion of the "fear" prophesied in ver. 15, and consequently prior in time to it. "Destitute," in ver. 17, is literally _naked_ or _stript_. It is used in Jer. xvii. 6 as the name of a desert plant, probably a dwarf juniper, stunted and dry, but seems to be employed here as simply designating utter destitution. Israel had been stripped of every beauty and made naked before her enemies. Despised, she had cried to God, and now is clothed again with the garments of salvation, "as a bride adorneth herself with her jewels."
A wondering world will adore her delivering God. The glowing hopes of psalmist and prophet seem to be dreams, since the restored Israel attracted no such observance and wrought no such convictions. But the singer was not wrong in believing that the coming of Jehovah in His glory for the rebuilding of Zion would sway the world to homage. His facts were right, but he did not know their perspective, nor could he understand how many weary years lay, like a deep gorge hidden from the eye of one who looks over a wide prospect, between the rebuilding of which he was thinking, and that truer establishment of the city of God, which is again parted from the period of universal recognition of Jehovah's glory by so many sad and stormy generations. But the vision is true. The coming of Jehovah in His glory will be followed by a world's recognition of its light.
That praise accruing to Jehovah shall be not only universal, but shall go on sounding, with increasing volume in its tone, through coming generations. This expectation is set forth in vv. 18-22, which substantially reiterate the thought of the preceding, with the addition that there is to be a new Israel, a people yet to be created (Psalm xxii. 31). The psalmist did not know "the deep things he spoke." He did know that Israel was immortal, and that the seed of life was in the tree that had cast its leaves and stood bare and apparently dead. But he did not know the process by which that new Israel was to be created, nor the new elements of which it was to consist. His confidence teaches us never to despair of the future of God's Church, however low its present state, but to look down the ages, in calm certainty that, however externals may change, the succession of God's children will never fail, nor the voice of their praise ever fall silent.
The course of God's intervention for Israel is described in vv. 19, 20. His looking down from heaven is equivalent to His observance, as the all-seeing Witness and Judge (compare Psalms xiv. 2, xxxiii. 13, 14, etc.), and is preparatory to His hearing the sighing of the captive Israel, doomed to death. The language of ver. 20 is apparently drawn from Psalm lxxix. 11. The thought corresponds to that of ver. 17. The purpose of His intervention is set forth in vv. 21, 22, as being the declaration of Jehovah's name and praise in Jerusalem before a gathered world. The aim of Jehovah's dealings is that all men, through all generations, may know and praise Him. That is but another way of saying that He infinitely desires, and perpetually works for, men's highest good. For our sakes, He desires so much that we should know Him, since the knowledge is life eternal. He is not greedy of adulation nor dependent on recognition, but He loves men too well not to rejoice in being understood and loved by them, since Love ever hungers for return. The psalmist saw what shall one day be, when, far down the ages, he beheld the world gathered in the temple-courts, and heard the shout of their praise borne to him up the stream of time. He penetrated to the inmost meaning of the Divine acts, when he proclaimed that they were all done for the manifestation of the Name, which cannot but be praised when it is known.
