Firmament in the Bible

The Word in Genesis 1

Genesis 1:6–8 — "And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which [were] under the firmament from the waters which [were] above the firmament: and it was so. And God called the firmament Heaven."

"Firmament" is the KJV's translation of the Hebrew word raqia (רָקִיעַ, Strong's H7549) — one of the more contested words in the Hebrew Bible for translators across the centuries.

The Hebrew Root

The noun raqia comes from the verb raqa (רָקַע, H7554), meaning "to beat out, to stamp, to hammer thin, to spread out by beating." The verb is used of metalwork — for example, of beating gold into thin sheets:

• Exodus 39:3 — "And they did beat the gold into thin plates" — the verb is raqa.
• Numbers 16:39 — "made broad plates [for] a covering of the altar" — participle of raqa.
• Job 37:18 — "Hast thou with him spread out the sky, [which is] strong, [and] as a molten looking glass?" — uses raqa for stretching the sky.

So raqia is literally "something hammered out" or "a beaten-out expanse." The name derives from the action of spreading or flattening by pressure.

How the Word Was Translated

The translation history of raqia shows how ancient translators tried to render a picture their target language had no ready word for:

• Septuagint (Greek, 3rd century BC) — stereōma (στερέωμα), "a solid, firm thing." From stereos ("hard, solid").
• Latin Vulgate (Jerome, 4th century AD) — firmamentum, "a firm support." From Latin firmus ("strong, stable"). This Latin rendering is where "firmament" in English comes from.
• KJV (1611) — "firmament," following the Vulgate.
• Modern English translations — usually "expanse" (ESV, NASB, NET, NIV has "vault"), emphasizing the verb's primary sense of spreading out.

Ancient Near Eastern Cosmology

The worldview within which Genesis 1 was first composed included a specific picture of the sky. Ancient Near Eastern cosmologies — Babylonian, Egyptian, Canaanite — typically pictured a solid dome over a flat earth:

• Waters below — seas, springs, rivers, and the subterranean "deep."
• A solid expanse — separating the waters below from waters above.
• Waters above — the source of rain, held back by the dome.
• Windows or openings in the dome through which rain fell (Genesis 7:11: "the windows of heaven were opened").
• Heavenly bodies — sun, moon, stars — set in or moving across the expanse (Genesis 1:14–18).

Genesis 1 uses this picture. The raqia is described as dividing waters above from waters below (v. 7), as the place where God sets the sun, moon, and stars (v. 14, 17), and as the space where birds fly across its face (v. 20). The description is phenomenological — it describes the sky as it appears from the ground — and uses the shared ancient vocabulary.

How to Read This as a Modern Reader

Modern readers encounter a tension. Ancient cosmology's solid dome does not match modern astronomy's atmosphere plus vacuum plus distant celestial bodies. Three main approaches:

• Phenomenological reading — Scripture accommodates ancient language about visible phenomena without affirming their underlying physical mechanics. The same pattern occurs in modern usage: we still speak of "sunrise" and "sunset" without affirming geocentrism. Genesis is not trying to teach physics; it is asserting that God is the creator and orderer of the whole.
• Concordist reading — the Hebrew raqia is compatible with the atmosphere or with the broader celestial expanse. The core claim ("God made the firmament") is compatible with multiple physical pictures of what that firmament actually is.
• Concessionary reading — the text describes a cosmology now known to be inaccurate in its physical details, but the theological claim (God's sovereignty in creation) stands independent of the ancient-science scaffolding.

Other Biblical Uses of Raqia

• Psalm 19:1 — "The heavens declare the glory of God; and the firmament sheweth his handywork."
• Psalm 150:1 — "Praise him in the firmament of his power."
• Ezekiel 1:22, 25, 26 — Ezekiel's vision of the divine chariot features a raqia above the living creatures, on which the throne of God rests.
• Daniel 12:3 — "they that be wise shall shine as the brightness of the firmament."

Summary

• Firmament — KJV rendering of Hebrew raqia, from the verb raqa ("to hammer out, to spread by beating").
• The Septuagint rendered it stereōma ("solid"); the Vulgate, firmamentum.
• In Genesis 1, it divides waters above from waters below, and the heavenly bodies are set in it.
• The picture draws on ancient Near Eastern cosmology; modern readers approach the text through phenomenological, concordist, or concessionary readings.
• The theological core — God as creator and orderer — stands regardless of physical-cosmological reading.
