Thou sendest forth thy spirit, they are created - That is, New races are created in their place, or start up as if they were created directly by God. They derive their being from him as really as those did which were first formed by his hand, and the work of creation is constantly going on.
And thou renewest the face of the earth - The earth is not suffered to become desolate. Though one generation passes off, yet a new one is made in its place, and the face of the earth constantly puts on the aspect of freshness and newness.

Thou sendest forth thy spirit, they are created - יבראון yibbareun, "They are created again."
And thou renewest the face of the earth - Do not these words plainly imply a resurrection of the bodies which have died, been dissolved, or turned to dust? And is not the brute creation principally intended here? Is it not on this account it is said, Psalm 104:31, "the glory of the Lord shall endure for ever, (לעולם leolam)," to be manifest in those times which are secret, when Jehovah himself shall rejoice in his works; when the brute creation shall be delivered from the bondage of its corruption? See the notes on Romans 8:19-23 (note).

Thou (q) sendest forth thy spirit, they are created: and thou renewest the face of the earth.
(q) As the death of creatures shows that we are nothing of ourselves: so their generation declares that we receive all things from our Creator.

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.

Spirit - That quickening power of God, by which he produces life in the creatures from time to time. For he speaks not here of the first creation, but of the continued production of living creatures. Created - Other living creatures are produced; the word created being taken in its largest sense for the production of things by second causes. Renewest - And thus by thy wise and wonderful providence thou preservest the succession of living creatures.
