Isaiah 42:5

It says, "He who gives spirit to the people who are on the earth, and spirit to them who walk on it." For undoubtedly every one who walks on the earth, that is, every earthly and corporeal being, is a partaker of the Holy Spirit that he receives from God.

The name by which he will be praised as the Lord and God of all, [Isaiah] says, "I will give to no other" but to you alone, whom I shall grant to be light to the nations. Hence, in the promise the Christ of God is called Lord and God by all the nations, the Father having granted him alone that glory. Next comes "nor will I give my powers to the carved images," or, according to Aquila, "my worship to carved images," or, with Symmachus, "my praise to carved images." … According to this, Christ alone is called God since to him alone and to no other has God, who is above all things, given his glory and power.

And again, "who gave breath to the people on the earth and spirit to those walking on it." For at first the soul, that is, "breath," was given to the people who go around on the earth, that is, to those acting in flesh in a fleshly manner; then later the Spirit was given to those who walk on the earth, that is, those who subdue the works of the flesh, as the apostle affirms, "Not that which is spiritual first, but that which is animal and then that which is spiritual." For although Adam from the beginning prophesied that great mystery in Christ and the church, "this is now bone of my bone and flesh of my flesh, on which account a man will leave his father and mother and cleave to his wife and they two will become one flesh," he was subject to a falling of the spirit.

Isaiah again says: Thus saith the Lord, he that made the heaven and pitched it; and the Apostle in like manner says: Of the true Tabernacle which the Lord pitched and not man. They both speak of the heaven as standing on and fixed on …

(Verse 5) Thus says the Lord God: He who creates the heavens and stretches them out, who spreads out the earth with all that springs from it, who gives breath to its people, and life to those who walk on it. It was uncertain who has said before: Behold my servant, I will take him: my chosen, my soul has pleased him. I have put my spirit upon him: he shall bring forth judgment to the Gentiles. After the condemnation of idols, a sudden speech had burst forth. Behold my servant, and the rest, which we have interpreted from the Father's perspective on Christ. Therefore, to not leave it ambiguous who said the previous things, he adds and says: Thus says the Lord God, creating the heavens and stretching them out. Or as the Septuagint translated: He made the heaven and fixed it. Therefore, the Creator and Lord of the universe himself promised the coming of his Christ, who not only stretched out and fixed the heavens, but also established the earth with its lofty mass, and everything that springs forth from it, so that the invisible things of him may be understood and seen from the things that are made (Rom. I); as well as his everlasting power and divinity. He who gave breath to all who dwell on earth, the first law of mortals. For God breathed into the face of Adam the breath of life, and he became a living soul (Gen. II). But the Spirit properly belongs to those who tread upon the earth; and the wisdom of the flesh subjects itself to its own power.
