Psalms 33:6

Effort and time on the part of workers was not required: a word was sufficient for creating on his part. He said, Let a firmament be made, and so it was. Let lights be made in the firmament of heaven, and it was. Such is …

The Trinity is clearly declared here: Lord, Word, Spirit of the Lord.

There is clear demonstration in this verse that the Father, the Son and the Holy Spirit are the creators of all things.

Where are those who set at naught the Spirit? Where are those who separate it from the creative power? Where are those who dissever it from union with the Father and Son? Let them hear the psalm that says, "By the word of the Lord the heavens were established; and all the power of them by the spirit of his mouth." The term "Word" will not be considered as this common form of diction that consists of names and expressions; nor will the Spirit be considered as vapor poured out in the air but as the Word, which was in the beginning with God, and as the Holy Spirit, which has obtained appellation as its own. As, then, the Creator, the Word, firmly established the heavens, so the Spirit, which is from God, which proceeds from the Father, that is, which is from his mouth (that you may not judge that it is some external object or some creature but may glorify it as having its substance from God) brings with it all the powers in him.… Since, then, the Savior is the Word of the Lord and the Holy Spirit is the Spirit from his mouth, both joined with him in the creation of the heavens and the powers in them, and for this reason the statement was made: "By the word of the Lord the heavens were established; and all the power of them by the spirit of his mouth." For nothing is made holy except by the presence of the Spirit.

If we examine the passage more carefully, he even indicates the holy Trinity here. For by using the term word he reveals the Son, by adding "of the Lord" he speaks of the Father, and with the phrase "by the spirit of his mouth" he …

By the word of the Lord were the heavens made solid; because made from the waters—for in no passage elsewhere is the [heaven] said to be solid; it is one thing to be made solid, and another to be solid. The expression being made solid …

By the "word" we must here understand the Son, through whom, as St. John declares, "all things were made." And what is "the spirit of his mouth" if not the Spirit whom we believe to be holy? Thus, in one text, you have the Lord, …

By the word of the Lord the heavens were established; and all the power of them by the spirit of His mouth. The heavens, that is the heavenly beings, were confirmed through faith by the Word of God; and through this same Word, both the …

In words, that appears especially efficacious for testifying which David, the most excellent of the Prophets, said in the Psalm: By the Word of the Lord the heavens were established, and by the Spirit of His mouth all their power, where the trinity of persons …

Concerning this Spirit it is written: "His Spirit has adorned the heavens." For the ornaments of the heavens are the virtues of those who preach. Paul enumerates these ornaments, saying: "To one is given through the Spirit the word of wisdom, to another the word of knowledge according to the same Spirit, to another faith in the same Spirit, to another the grace of healing in one Spirit, to another the working of miracles, to another prophecy, to another the discernment of spirits, to another various kinds of tongues, to another the interpretation of speeches. But one and the same Spirit works all these things, distributing to each one individually as He wills." Therefore, as many as are the gifts of those who preach, so many are the ornaments of the heavens. Hence it is written again: "By the word of the Lord the heavens were established." For the Word of the Lord is the Son of the Father. But concerning these same heavens, namely the holy apostles, so that the entire holy Trinity might be shown to have worked together, it is suddenly added concerning the divinity of the Holy Spirit: "And by the breath of His mouth is all their power." Therefore the power of the heavens was received from the Spirit, because they would not have presumed to oppose the powers of this world unless the strength of the Holy Spirit had made them firm.

Then when he says, "By the word," the cause of joy is set forth on the part of the divine effects. Moses at the beginning of the creation of things makes mention of three: heaven, water, and earth: Gen. 1: "In the beginning God created …

Now a spirit that is sent, and acts, and strengthens and maintains is not breath that is dissipated any more than the mouth of God is a bodily member. Both in fact are to be understood as appropriately referring to God.

The word - God made this admirable structure of the heavens, and all its glorious stars; not with great pains and time, but with one single word. Host - The angels: or the stars.

By the word of the Lord were the heavens made,....

By the word of the Lord were the heavens made. The angelic heavens, the sidereal heavens, and the firmament or terrestrial heavens, were all made to start into existence by a word; what if we say by the Word, "For without him was not anything made that is made." It is interesting to note the mention of the Spirit in the next clause, and all the host of them by the breath of his mouth; the breath is the same as is elsewhere rendered Spirit. Thus the three persons of the Godhead unite in creating all things.

Reasons for praise: first, God's truth, faithfulness, and mercy, generally; then, His creative power which all must honor.

By the word of the Lord were the heavens made. The angelic heavens, the sidereal heavens, and the firmament or terrestrial heavens, were all made to start into existence by a word; what if we say by the Word, "For without him was not anything made that is made." It is interesting to note the mention of the Spirit in the next clause, and all the host of them by the breath of his mouth; the breath is the same as is elsewhere rendered Spirit. Thus the three persons of the Godhead unite in creating all things. How easy for the Lord to make the most ponderous orbs, and the most glorious angels! A word, a breath could do it. It is as easy for God to create the universe as for a man to breathe, nay, far easier, for man breathes not independently, but borrows the breath in his nostrils from his Maker. It may be gathered from this verse that the constitution of all things is from the infinite wisdom, for his word may mean his appointment and determination. A wise and merciful Word has arranged, and a living Spirit sustains all the creation of Jehovah.

By the word of the Lord were the heavens made - This is illustrated in the Psa 33:9 verse: “He spake, and it was done; he commanded, and it stood fast.” This evidently refers to the account of the creation, as it stands in the first chapter of Genesis.

By the word of the Lord - By the command of God: Gen 1:3, Gen 1:6 etc. See the notes at Psa 33:9. Were the heavens made - That is, the starry heavens; the worlds above us: Gen 1:1. And all the host of them - All their “armies.” The stars are represented as armies or marshalled hosts, led forth at his command, and under his direction - as armies are led forth in war. See Gen 2:1; compare the notes at Isa 1:9. By the breath of his mouth - By his word or command - as our words issue from our mouths with our breath. The idea here is, that God is the Creator of all things; and, as such, has a claim to praise; or, that as Creator he is entitled to adoration. To this he is entitled from the fact that he has made all things, and from the “manner” in which it has been done - the wisdom, power, goodness, skill, with which it has been accomplished.
