Genesis 1:8 Commentary: The Second Day, Expanse, Sky, Omission of 'Good'
Hebrew · 7 what the commentators say
Meaning in one sentence
Why is 'God saw that it was good' missing on the second day? What did the Hebrews mean by firmament? A detailed study of Genesis 1:8.
Research Summary
- Meaning: God creates the firmament (expanse) to separate waters, calls it Heaven, and completes the second day, but does not yet pronounce it “good.”
- Key words: “Expanse” (raqia) from a verb meaning “spread out”; “Heaven” (shamayim) as the visible sky; “second day” using the ordinal sheni.
- Main debate: Whether the missing “God saw that it was good” is a textual error (LXX addition) or an intentional silence, reflecting incomplete work on the waters.
- Theological theme: God’s sovereign ordering of creation through separation and naming; the tension between completed action and deferred approval.
- Best use: A text for sermons on divine patience, the value of process, and the trustworthiness of God’s Word even when it raises questions.

Scholars' Consensus
Commentators across traditions agree that on the second day God set apart an expanse (Hebrew raqia, from raqa, “spread out by beating, as leaf gold”) to divide the waters. This expanse God called “Heaven” (or “sky”). The most striking feature is the absence of the formula “God saw that it was good,” which appears on every other creation day. Cambridge Bible notes that the Septuagint adds the phrase, suggesting a possible textual error. Gill’s Exposition cites the Jewish rabbi Jarchi: the work of the waters was not finished on day two, it would be completed on day three, when the dry land appears; hence the approval is delayed and given twice on day three. Barnes and Keil & Delitzsch both emphasize that the raqia was not understood by the Hebrews as a solid dome, despite the Vulgate’s firmamentum. Rather, it is the atmosphere that supports clouds and birds. The day’s structure, evening and morning, marks a second 24-hour period (Wesley, Matthew Henry).
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Textual loss view: The Septuagint includes “God saw that it was good,” and the pattern of other days makes this likely original. Cambridge Bible supports this.
- Deliberate omission view: The work of the waters was unfinished; approval is withheld until day three when it is given twice. Jarchi via Gill and Matthew Henry note this.
- Theological silence view: The omission is neither error nor incompleteness but a rhetorical device pointing to the heavenly realm as a place not subject to human judgment of 'goodness.'
What is clear: God created the firmament, named it Heaven, and the second day was completed; the formula 'God saw that it was good' is absent from the Hebrew text, and interpreters have long sought to understand why.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Omission of 'God saw that it was good' | All traditions note the absence of this phrase on day two, unlike other days. | Some (Cambridge, many modern scholars) see a scribal error; the Septuagint supplies the phrase. Others (Jarchi via Gill, Matthew Henry) view it as deliberate: the waterwork was unfinished until day three. |
| Nature of the firmament (raqia) | The firmament is a divinely created expanse that separates waters and is called heaven/sky. | Ancient Hebrews likely conceived it as solid (lexicon, Cambridge, K&D mention the common view), but many commentators (K&D, Barnes, Matthew Henry) argue the biblical text itself does not require a solid dome; poetic descriptions are figurative. |
| Interpretation of 'waters above' | The waters above the firmament are distinct from the waters below and are part of God's ordered creation. | Some see them as literal atmospheric waters (clouds, vapor), while others (ancient and some modern) interpret them as a celestial reservoir or a component of the cosmic structure described poetically elsewhere. |
| Length of creation days | The 'evening and morning' framework defines each day as a unit of time. | Most traditional commentators (Gill, Wesley, Henry) understand them as 24-hour days. Others (including some modern interpreters) allow for non-literal 'days' or long periods, though this is not the focus of the supplied sources. |
Historical & Cultural Context
Genesis 1:8 crowns the second day of creation, a day focused on ordering the chaotic waters that covered the earth. In the ancient Near East, other creation accounts (like the Babylonian Enuma Elish) describe a violent division of a sea goddess to form sky and earth. Genesis presents a quiet, sovereign word: “Let there be an expanse.” There is no struggle, no battle, just command and result.
The Hebrew term raqia carries the sense of something beaten out or spread, like a metal sheet or a tent curtain. Matthew Henry and Wesley note that this expanse includes everything visible above the earth, the air, the celestial bodies, and the vault of the sky. Crucially, the expanse is not presented as a solid ceiling. Keil & Delitzsch argue that poetical descriptions in Job, Psalms, and Isaiah (e.g., “stretching out the heavens like a curtain”) should not be pressed into a literal cosmology. The “waters above the firmament” (v. 7) refer to moisture held in clouds and vapors, not a mythical ocean.
The omission of “it was good” may reflect that the dividing of waters was an intermediate step. The waters beneath had not yet been gathered into seas; that would happen on day three, when the formula appears twice (Genesis 1:10, 12). The naming of the expanse as “Heaven” establishes it as a defined province in God’s ordered creation, a home for birds and later for the lights of day four.
Textual Notes
The consulted sources note no significant textual variants in the Masoretic Text of Genesis 1:8. The most important textual issue is the omission of “God saw that it was good” on the second day. The Septuagint adds the phrase after “Heaven,” and the Cambridge Bible suggests it may have fallen out of the Hebrew text through scribal error. The Dead Sea Scrolls and other witnesses provide no evidence for this reading. The omission is therefore either original or an early loss; no manuscript support exists for the phrase in the Hebrew tradition.
Reception History
Early Jewish interpretation (e.g., the Targums) and rabbinic sources (Jarchi) wrestled with the missing divine approval, often linking it to the incomplete work of dividing waters. The Septuagint translators felt the gap keenly enough to supply “good.” In the Christian tradition, the Vulgate’s firmamentum shaped medieval cosmology, where the firmament was pictured as a solid vault. Reformers like Luther and Calvin followed the plain sense of the text but did not elaborate on the omission. Matthew Henry and Wesley, writing in the 18th century, treated the missing phrase as a teaching moment about process. Modern scholarly commentary (Barnes, K&D, Cambridge) has shifted toward understanding the raqia as the atmosphere, not a dome, while still respecting the literary pattern of approval deferred.
Preaching This Verse
Three-point outline
- God's word brings order out of chaos. The expanse separates the waters, imposing structure on what was formless. The same God speaks into our confusion today.
- God names what he makes. Calling the expanse “Heaven” declares its purpose and place. Naming is an act of authority and relationship.
- Not everything is finished on day two. The missing “good” reminds us that some work remains incomplete, but God’s timing is perfect. He completes what he begins (Psalm 138:8).
Five-point outline
- The command: “Let there be an expanse”, God speaks, and space is created for life to thrive.
- The separation: Waters above from waters below, God sets boundaries that allow the earth to become habitable.
- The construction: “God made the expanse”, divine action follows divine word; God does what he says.
- The naming: “He called… Heaven”, every element of creation has meaning and order under God’s rule.
- The completion: “Evening and morning, second day”, a full cycle of work and rest, yet with a note of anticipation.
Illustration hooks
- The feeling of a day’s work that feels unfinished, like building a fence but needing another day to set the gate. The second day is “good” in part, but the full “very good” waits for day six.
- When we look up at a clear blue sky, we see the expanse that centuries of believers have called “heaven.” It’s both a physical sky and a reminder of God’s sovereignty above.
- A chef preparing a complex meal may not taste each step; only the final dish receives the full approval. So God withholds ultimate pronouncement until the work is complete.
Questions your congregation is asking
- If God didn’t call the second day “good,” does that mean it wasn’t perfect? Or does it teach us something about patience with processes?
- How should we understand the “waters above” in a scientific age? Does this passage require a three-tier universe, or can it speak to deeper truths?
- What does it mean that God “calls” things? How does his naming of creation connect to his naming of us (Isaiah 43:1)?
Leading a Discussion
This verse is part of a carefully ordered creation narrative. The second day shows God imposing structure on a watery chaos, yet it lacks the usual divine approval. This gap invites us to reflect on how God works, and how we wait for completion.
Discussion questions
- Observation: What did God do on the second day, according to verses 6-8? What specific actions are described?
- Observation: Compare the second day with the first day (v. 5) and the third day (vv. 9-13). What pattern do you notice about the phrase “God saw that it was good”?
- Interpretation: The commentators offer several reasons for the missing phrase. Which explanation resonates with you, textual error, unfinished work, or something else? Why?
- Interpretation: The word raqia can mean “expanse” or “something spread out.” How does the Bible’s own poetic language (e.g., Isa 40:22, Job 37:18) help us understand what is being described?
- Interpretation: God names the expanse “Heaven” (sky). In the Bible, naming often signifies authority and relationship. How does God’s naming of creation connect to his naming of people (e.g., Abraham, Peter)?
- Application: Think of an area of your life that feels “incomplete” or not yet approved. How does seeing the second day as a stage in God’s good plan give you patience or hope?
- Application: The creation days move from chaos to order, from darkness to light, from water to land. Where do you need to trust that God is bringing order to turmoil in your world?

What the Commentators Say
7 public-domain commentaries, condensed into plain language.
Barnes' Notes on the Bible Protestant 1832
Barnes reads the second day of creation as God ordering the chaotic mixture of water and vapor. He explains the "expanse" as the atmosphere, a breathing space that separates the liquid waters below from the cloud waters above, a rearrangement of existing materials rather than a new creation.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator argues that the Hebrew word "Heaven" meant a solid arch, not clouds or empty space. He suggests the missing "God saw that it was good" after the second day is probably a scribal error, since the Greek Septuagint includes that phrase.
Geneva Bible Notes Reformed 1599
The Geneva note simply repeats the biblical text, affirming that God named the expanse Heaven and that the evening and morning marked the close of the second day. It offers no additional interpretation or explanation.
Gill's Exposition of the Bible Baptist 1748
Gill notes that the phrase "God saw that it was good" is missing from the account of the second day. He explains that Jewish commentators like Jarchi attribute this to the work of the waters being unfinished, begun on the second day and completed on the third.
Keil & Delitzsch OT Commentary Protestant 1876
Keil and Delitzsch identify the waters above the firmament not as a cosmic ocean or material for stars, but as the rain-bearing clouds contained in the atmosphere. They ground this in the Old Testament picture of rain falling when heaven's windows open, treating the vault of the sky as the everyday divider of earthly and aerial waters.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry emphasizes that the firmament is not a barrier separating heaven from earth but a medium for communication between them. He also notes that God not only commanded the firmament into existence but personally made it, teaching that what God requires of us He Himself works in us.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley notes that "firmament" means an expansion, like a sheet stretched out, covering everything from the air where birds fly to the realm of the stars. He stresses its role in dividing the waters above (clouds) from the waters below (seas), and calls it "Heaven" to remind us of God's supremacy, holiness, and universal providence.
