(30) Spirit.--Rather, breath, as in Psalm 104:29. We must not here think of the later theological doctrine of the Holy Spirit. The psalmist evidently regards the breath of God only as the vivifying power that gives matter a distinct and individual, but transient, existence. Even in the speculative book of Ecclesiastes, the idea of a human soul having a permanent separate existence does not make its appearance. At death the dust, no longer animate, returns to the earth as it was, and the breath, which had given it life, returns to God who gave it--gave it as an emanation, to be resumed unto Himself when its work was done. Still less, then, must we look in poetry for any more developed doctrine.

Verse 30. - Thou sendest forth thy spirit; or, thy breath. As God "breathed into man's nostrils the breath of life" (Genesis 2:7), so it is an effluence from him that gives life to every living thing. They are created: and thou renewest the face of the earth. As after the Deluge (see Genesis 7:4; Genesis 8:17).

104:19-30 We are to praise and magnify God for the constant succession of day and night. And see how those are like to the wild beasts, who wait for the twilight, and have fellowship with the unfruitful works of darkness. Does God listen to the language of mere nature, even in ravenous creatures, and shall he not much more interpret favourably the language of grace in his own people, though weak and broken groanings which cannot be uttered? There is the work of every day, which is to be done in its day, which man must apply to every morning, and which he must continue in till evening; it will be time enough to rest when the night comes, in which no man can work. The psalmist wonders at the works of God. The works of art, the more closely they are looked upon, the more rough they appear; the works of nature appear more fine and exact. They are all made in wisdom, for they all answer the end they were designed to serve. Every spring is an emblem of the resurrection, when a new world rises, as it were, out of the ruins of the old one. But man alone lives beyond death. When the Lord takes away his breath, his soul enters on another state, and his body will be raised, either to glory or to misery. May the Lord send forth his Spirit, and new-create our souls to holiness.Thou sendest forth thy Spirit, they are created,.... Thy Holy Spirit, as the Targum, who was at first concerned in the creation of all things, the heavens and the earth, and man upon it, Genesis 1:2, Job 26:13 which may be alluded to here; though it seems chiefly to intend the generation and production of creatures in the room of those that die off; that so their species may be preserved, and there may be a constant succession of them, as there is in all ages, Ecclesiastes 1:4.

And thou renewest the face of the earth; by a new set of creatures of all kinds being brought upon it to fill it. As there is also a daily renewing it every morning by the rising sun, giving fresh life and vigour to all created beings; and a yearly one every spring, when the face of all nature is renewed and revived. Jarchi and Arama understand it of the resurrection of the dead; this sense Kimchi mentions as an article of their faith, but not as the sense of the text. It may be applied to the renewing work of the Spirit of God in the souls of men, by whom they are made new, and by whom they are daily renewed in the Spirit of their minds. And there are particular seasons in which God sends forth his Spirit and renews the face of things in the world, and in his churches; upon the effusion of his Spirit in the first times of the Gospels, there was a new face of things, not only in the land of Judea, but throughout the whole Gentile world, where old things passed away, and all things became new; as in the latter day, when the Spirit shall be poured forth from on high, there will be a renewing of the face of the earth again; it will be filled with the knowledge of the Lord as the waters cover the sea; the kingdoms of it will become Christ's; new heavens and a new earth will be created, and Jerusalem will be made a rejoicing, and her people a joy, Isaiah 65:17.
