Thus says God the LORD, he that created the heavens, and stretched them out; he that spread forth the earth, and that which comes out of it; he that gives breath unto the people upon it, and spirit to them that walk in it:

The Son is both sent and given, and the Spirit also is both sent and given; they have assuredly a oneness of Godhead who have a oneness of action. - "On the Holy Spirit 3.2.10"
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. - "Commentary on Isaiah 2.22"
The breath of life, which also rendered man [a person] an animated being, is one thing, and the vivifying Spirit another, which also caused him to become spiritual. And for this reason Isaiah said, “Thus says the Lord, who made heaven and established it, who founded the earth and the things therein, and gave breath to the people on it and the Spirit to those walking on it”; thus telling us that breath is indeed given in common to all people on earth but that the Spirit is theirs alone who tread down earthly desires. - "Against Heresies 5.12.2"
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. - "On the Soul 11.3–4"
