Commentary on Genesis 1 verses 6–8
We have here an account of the second day's work, the creation of the firmament, in which observe, 1. The command of God concerning it: Let there be a firmament, an expansion, so the Hebrew word signifies, like a sheet spread, or a curtain drawn out. This includes all that is visible above the earth, between it and the third heavens: the air, its higher, middle, and lower, regions - the celestial globe, and all the spheres and orbs of light above: it reaches as high as the place where the stars are fixed, for that is called here the firmament of heaven (Gen 1:14, Gen 1:15), and as low as the place where the birds fly, for that also is called the firmament of heaven, Gen 1:20. When God had made the light, he appointed the air to be the receptacle and vehicle of its beams, and to be as a medium of communication between the invisible and the visible world; for, though between heaven and earth there is an inconceivable distance, yet there is not an impassable gulf, as there is between heaven and hell. This firmament is not a wall of partition, but a way of intercourse. See Job 26:7; Job 37:18; Psa 104:3; Amo 9:6. 2. The creation of it. Lest it should seem as if God had only commanded it to be done, and some one else had done it, he adds, And God made the firmament. What God requires of us he himself works in us, or it is not done. He that commands faith, holiness, and love, creates them by the power of his grace going along with his word, that he may have all the praise. Lord, give what thou commandest, and then command what thou pleasest. The firmament is said to be the work of God's fingers, Psa 8:3. Though the vastness of its extent declares it to be the work of his arm stretched out, yet the admirable fineness of its constitution shows that it is a curious piece of art, the work of his fingers. 3. The use and design of it - to divide the waters from the waters, that is, to distinguish between the waters that are wrapped up in the clouds and those that cover the sea, the waters in the air and those in the earth. See the difference between these two carefully observed, Deu 11:10, Deu 11:11, where Canaan is upon this account preferred to Egypt, that Egypt was moistened and made fruitful with the waters that are under the firmament, but Canaan with waters from above, out of the firmament, even the dew of heaven, which tarrieth not for the sons of men, Mic 5:7. God has, in the firmament of his power, chambers, store-chambers, whence he watereth the earth, Psa 104:13; Psa 65:9, Psa 65:10. He has also treasures, or magazines, of snow and hail, which he hath reserved against the day of battle and war, Job 38:22, Job 38:23. O what a great God is he who has thus provided for the comfort of all that serve him and the confusion of all that hate him! It is good having him our friend, and bad having him our enemy. 4. The naming of it: He called the firmament heaven. It is the visible heaven, the pavement of the holy city; above the firmament God is said to have his throne (Eze 1:26), for he has prepared it in the heavens; the heavens therefore are said to rule, Dan 4:26. Is not God in the height of heaven? Job 22:12. Yes, he is, and we should be led by the contemplation of the heavens that are in our eye to consider our Father who is in heaven. The height of the heavens should remind us of God's supremacy and the infinite distance there is between us and him; the brightness of the heavens and their purity should remind us of his glory, and majesty, and perfect holiness; the vastness of the heavens, their encompassing of the earth, and the influence they have upon it, should remind us of his immensity and universal providence.
Although God had already previously made heaven, now he makes the firmament. For he made heaven first, about which he says, “Heaven is my throne.” But after that he makes the firmament, that is, the corporeal heaven. For every corporeal object is, without doubt, firm and solid; and it is this that “divides the water which is above heaven from the water which is below heaven.”
Although God said about the light that came to be on the first day that "it was very good," He did not say this about the firmament which came to be on the second day, because the firmament had not yet been finished, neither in its structure nor in its adornment. The Creator delayed until the lights came to be so that when [ the firmament ] was adorned with the sun and the moon and the stars, and the strength of the darkness that was weakened by the lights shining from it, He would then say of the firmament as well as of [ the rest of creation ] that "it was very good."
Since Scripture called heaven the firmament, we can without absurdity hold that anything below the ethereal heaven, in which everything is peaceful and stable, is more mutable and perishable and is a kind of corporeal matter prior to the reception of beauty and the distinction of forms.
And if the words, "God saw that it was good," are not said of the work of the second day, this is because the work of distinguishing the waters was only begun on that day, but perfected on the third. Hence these words, that are said of the third day, refer also to the second. Or it may be that Scripture does not use these words of approval of the second days' work, because this is concerned with the distinction of things not evident to the senses of mankind. Or, again, because by the firmament is simply understood the cloudy region of the air, which is not one of the permanent parts of the universe, nor of the principal divisions of the world. The above three reasons are given by Rabbi Moses [Perplex. ii.], and to these may be added a mystical one derived from numbers and assigned by some writers, according to whom the work of the second day is not marked with approval because the second number is an imperfect number, as receding from the perfection of unity.

SUMMARY
Genesis 1:8 culminates the second day of creation, detailing God's authoritative act of naming the newly formed expanse "Heaven." This divine declaration not only designates a crucial component of the cosmos but profoundly underscores God's meticulous design, sovereign control, and purposeful ordering of His unfolding creation, establishing the very atmospheric realm essential for life to thrive.
CONTEXT
EXPOSITION AND ANALYSIS
The second day of creation culminates with God's authoritative naming of the newly formed expanse and the formal conclusion of the day. This moment highlights God's absolute sovereignty, not merely in bringing things into existence, but in defining their very nature and purpose within His meticulously ordered universe.
Key Word Analysis
Verse Breakdown
Literary Devices
Genesis 1:8 effectively employs several literary devices to convey its profound theological truths. The most prominent is Naming, where God's act of calling the firmament "Heaven" signifies His absolute authority, ownership, and the establishment of identity and purpose for His creation. This is not arbitrary labeling but a divine declaration that defines the essence of what has been made. The verse also utilizes Repetition through the recurring refrain, "And the evening and the morning were the second day." This formulaic phrase, used consistently throughout the creation account, provides a clear structural rhythm, emphasizing the sequential and orderly nature of God's creative activity and marking the passage of time. Furthermore, the verse contributes to the overarching Progressive Revelation of God's creative power, building upon the initial act of separation on day one to establish distinct realms, demonstrating a deliberate and systematic unfolding of His cosmic design.
THEOLOGICAL AND THEMATIC CONNECTIONS
Genesis 1:8 profoundly illustrates God's absolute sovereignty and His meticulous design in bringing order to the cosmos. By creating the firmament and authoritatively naming it "Heaven," God demonstrates His power to separate, define, and establish distinct realms, transforming primordial chaos into a structured environment. This act is not arbitrary but intentional, preparing the earth for the flourishing of life by establishing the very atmospheric conditions necessary for its sustenance. The consistent rhythm of "evening and morning" further underscores God's faithfulness and the dependable nature of His created order, providing a foundational pattern for time itself and for humanity's subsequent rhythm of work and rest. This verse invites us to marvel at the intentionality and wisdom embedded in God's creative acts, recognizing that every element of creation serves His divine purpose.
REFLECTION AND APPLICATION
Genesis 1:8 invites us to gaze upon the sky with renewed awe, recognizing it not as a mere natural phenomenon but as a direct product of God's purposeful design and authoritative naming. Just as God brought order to the primordial waters and established the very atmosphere, He is capable of bringing clarity and purpose to the chaotic expanses of our own lives. This verse reminds us to trust in His meticulous plan and established rhythms, finding peace in the knowledge that the God who ordered the cosmos also orders our steps. It challenges us to consider how we might participate in bringing order and beauty to the spheres of influence God has given us, acknowledging His sovereignty over all things. Our lives, like the creation, are meant to reflect His order and purpose.
Questions for Reflection
FAQ
What exactly is the "firmament" God created?
Answer: The "firmament" (Hebrew: raqia') refers to the vast, stretched-out expanse of the atmospheric sky above the earth. It is the visible heavens, where clouds form and birds fly, serving to separate the waters on the earth's surface from the moisture in the clouds above, as described in Genesis 1:6-7. It creates the distinct breathable space that is essential for life.
Why is God's act of naming the firmament "Heaven" significant?
Answer: In biblical thought, naming is an act of sovereign authority, ownership, and definition. When God names something, He is not just giving it a label; He is asserting His ultimate prerogative as Creator, defining its essence, purpose, and destiny within His creation. This act signifies His complete control and intentionality, just as He named light "Day" and darkness "Night" in Genesis 1:5.
Does "the evening and the morning were the second day" imply a literal 24-hour day?
Answer: The recurring phrase "evening and morning" (Hebrew: ereb and boqer) strongly suggests a literal, chronological 24-hour day. This consistent pattern throughout the creation account, marked by the progression of darkness and light, establishes a divine rhythm for time. This understanding aligns with the later establishment of the weekly cycle of work and rest in the Mosaic Law, as seen in Exodus 20:11.
How does the work of the second day prepare for life on earth?
Answer: The creation of the firmament on the second day was a crucial preparatory step for life on earth. By separating the waters and establishing a distinct, breathable atmosphere, God created a stable and habitable environment. This atmospheric realm provides the necessary conditions for the emergence of plant, animal, and human life, allowing for the hydrological cycle, weather patterns, and the very air we breathe, all vital for sustenance and flourishing.
CHRIST-CENTERED FULFILLMENT
While Genesis 1:8 does not directly mention Christ, it profoundly reveals the nature of the Triune God, through whom all things were made and are sustained. Jesus Christ, as the eternal Word of God, was not merely present at creation but was the active agent, the very means by which the firmament was called into being and named "Heaven." As John 1:3 declares, "All things were made through Him, and without Him nothing was made that was made." The ordering, naming, and structuring seen on the second day point to the divine wisdom and power inherent in Christ, who is not only the Creator but also the sustainer of the cosmos, actively upholding all things by the word of His power, as affirmed in Colossians 1:16-17. He is the one who brings order to chaos, purpose to existence, and ultimately, through His redemptive work, brings spiritual order and new creation to those who believe, making all things new, just as He ordered the original creation.
