What does the Bible say about the heavens?
The Bible describes the firmament (Hebrew: "raqia") as a solid, hard structure above the Earth. The word comes from "raqa," which means to beat out or hammer thin - like a metalsmith hammering metal into a dome shape.
"Can you, like him, spread out the skies, hard as a cast metal mirror?"
"Over the heads of the living creatures there was the likeness of an expanse, shining like awe-inspiring crystal, stretched out above their heads."
"Then I looked, and behold, on the expanse that was over the heads of the cherubim there appeared above them something like a sapphire stone, in appearance resembling a throne."
"and they saw the God of Israel. There was under his feet as it were a pavement of sapphire stone, like the very heaven for clearness."
Analysis: The Bible consistently uses words like "hard," "crystal," "sapphire stone," and "cast metal" to describe this structure. This isn't empty space - it's described like a solid, jeweled pavement or mirror that can be seen and walked on.
The Bible uses tent and fabric language to describe how God made the firmament:
"covering yourself with light as with a garment, stretching out the heavens like a tent."
"It is he who sits above the circle of the earth, and its inhabitants are like grasshoppers; who stretches out the heavens like a curtain, and spreads them like a tent to dwell in;"
"Thus says the Lord, your Redeemer, who formed you from the womb: 'I am the Lord, who made all things, who alone stretched out the heavens, who spread out the earth by myself,'"
"I made the earth and created man on it; it was my hands that stretched out the heavens, and I commanded all their host."
"and have forgotten the Lord, your Maker, who stretched out the heavens and laid the foundations of the earth"
"It is he who made the earth by his power, who established the world by his wisdom, and by his understanding stretched out the heavens."
"It is he who made the earth by his power, who established the world by his wisdom, and by his understanding stretched out the heavens."
"The oracle of the word of the Lord concerning Israel: Thus declares the Lord, who stretched out the heavens and founded the earth and formed the spirit of man within him:"
Analysis: God repeatedly "stretched out" the heavens like fabric over a tent frame. This describes a covering stretched over the Earth.
On the second day of creation, God made this solid dome to divide water into two parts:
"And God said, 'Let there be an expanse in the midst of the waters, and let it separate the waters from the waters.' And God made the expanse and separated the waters that were under the expanse from the waters that were above the expanse. And it was so. And God called the expanse Heaven."
"Praise him, you highest heavens, and you waters above the heavens!"
"He lays the beams of his chambers on the waters; he makes the clouds his chariot; he rides on the wings of the wind;"
"The Lord sits enthroned over the flood; the Lord sits enthroned as king forever."
"For they deliberately overlook this fact, that the heavens existed long ago, and the earth was formed out of water and through water by the word of God,"
Analysis: There are literally waters sitting on top of the solid dome. A literal body of water exists above the firmament. During the flood, "windows of heaven" opened to release these waters through the solid dome.
Since it's a solid structure, the firmament has architectural openings:
"In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened."
"The fountains of the deep and the windows of the heavens were closed, and the rain from the heavens was restrained."
"Then the captain on whose hand the king leaned said to the man of God, 'If the Lord himself should make windows in heaven, could this thing be?'"
"And the captain had answered the man of God, 'If the Lord himself should make windows in heaven, could such a thing be?'"
"Bring the full tithe into the storehouse, that there may be food in my house. And thereby put me to the test, says the Lord of hosts, if I will not open the windows of heaven and pour down for you a blessing until there is no more need."
"Yet he commanded the skies above and opened the doors of heaven, and he rained down on them manna to eat and gave them the grain of heaven."
"After this I looked, and behold, a door standing open in heaven!"
"Then I saw heaven opened, and behold, a white horse!"
"Lift up your heads, O gates! And be lifted up, O ancient doors, that the King of glory may come in."
"Lift up your heads, O gates! And lift them up, O ancient doors, that the King of glory may come in."
Analysis: Windows, doors, and gates only make sense if there's a solid structure to put them in. These can be opened and closed to release water or allow passage. The firmament functions as a structure with operational openings.
The firmament is supported by foundations and pillars like a building:
"Then the earth reeled and rocked; the foundations of the heavens trembled and quaked, because he was angry."
"The pillars of heaven tremble and are astounded at his rebuke."
"Then the earth reeled and rocked; the foundations of the mountains trembled and quaked, because he was angry."
Analysis: The firmament has architectural support structures - foundations and pillars that can tremble and quake, indicating a solid, building-like structure.
The Bible says the sun, moon, and stars aren't distant objects in space - they're embedded in or attached to the solid dome:
"And God said, 'Let there be lights in the expanse of the heavens to separate the day from the night. And let them be for signs and for seasons, and for days and years, and let them be lights in the expanse of the heavens to give light upon the earth.' And it was so. And God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars. And God set them in the expanse of the heavens to give light on the earth"
"Their voice goes out through all the earth, and their words to the end of the world. In them he has set a tent for the sun, which comes out like a bridegroom leaving his chamber, and, like a strong man, runs its course with joy. Its rising is from the end of the heavens, and its circuit to the end of them, and there is nothing hidden from its heat."
"The sun rises, and the sun goes down, and hastens to its place where it arose."
"At that time Joshua spoke to the Lord in the day when the Lord gave the Amorites over to the sons of Israel, and he said in the sight of Israel, 'Sun, stand still at Gibeon, and moon, in the Valley of Aijalon.' And the sun stood still, and the moon stopped, until the nation took vengeance on their enemies."
"'Behold, I will make the shadow cast by the declining sun on the dial of Ahaz turn back ten steps.' So the sun turned back on the dial the ten steps by which it had declined."
Analysis: The phrase "set them in" means they're placed within or attached to the firmament structure. The sun has a "tent" in the firmament and can stop moving or go backwards. Luminaries are embedded within the dome.
This is why the Bible can describe stars falling to Earth:
"and the stars of the sky fell to the earth as the fig tree sheds its winter fruit when shaken by a gale."
"Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken."
"and the stars will be falling from heaven, and the powers in the heavens will be shaken."
"It grew great, even to the host of heaven. And some of the host and some of the stars it cast down to the ground and trampled on them."
"His tail swept down a third of the stars of heaven and cast them to the earth. And the dragon stood before the woman who was about to give birth, so that when she bore her child he might devour it."
Analysis: This only makes sense if stars are small objects attached to the dome that can break loose and fall down. Stars can "fall to earth," impossible if they were distant massive suns.
Above the water reservoir on top of the firmament is where God dwells:
"He lays the beams of his chambers on the waters; he makes the clouds his chariot; he rides on the wings of the wind;"
"The Lord is in his holy temple; the Lord's throne is in heaven; his eyes see, his eyelids test the children of man."
"Thus says the Lord: 'Heaven is my throne, and the earth is my footstool; what is the house that you would build for me, and what is the place of my rest?'"
"And listen to the plea of your servant and of your people Israel, when they pray toward this place. And listen in heaven your dwelling place, and when you hear, forgive."
"And above the expanse over their heads there was the likeness of a throne, in appearance like sapphire; and seated above the likeness of a throne was a likeness with a human appearance."
Analysis: God's dwelling place is above the waters that sit on top of the firmament. His chambers are built on the waters, and his throne is in heaven above the solid dome.
The firmament covers a circular, flat Earth with edges:
"It is he who sits above the circle of the earth, and its inhabitants are like grasshoppers; who stretches out the heavens like a curtain, and spreads them like a tent to dwell in;"
"He has inscribed a circle on the face of the waters at the boundary between light and darkness."
"He will raise a signal for the nations and will assemble the banished of Israel, and gather the dispersed of Judah from the four corners of the earth."
"After this I saw four angels standing at the four corners of the earth, holding back the four winds of the earth, that no wind might blow on earth or sea or against any tree."
"For he looks to the ends of the earth and sees everything under the heavens."
"Its rising is from the end of the heavens, and its circuit to the end of them, and there is nothing hidden from its heat."
"Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their glory."
Analysis: The Earth is described as circular with corners and ends, and from a high mountain one can see all the kingdoms of the world. This describes a flat, circular Earth with edges, not a spherical planet.
Ancient Jewish texts show this is how people understood the firmament for centuries:
"And on the second day He created the firmament in the midst of the waters, and the waters were divided on that day—half of them went up above and half of them went down below the firmament"
"I saw the winds on the earth carrying the clouds; I saw the paths of the angels. I saw at the end of the earth the firmament of the heaven above."
"And the Lord made the expanse, upbearing it with three fingers, between the confines of the heavens and the waters of the ocean, and separated between the waters which were below the expanse, and the waters which were above"
Targum Pseudo-Jonathan (Yerushalmi) Gen 1:7, Etheridge tr. (PDF)
"Rakia, firmament, is the one in which the sun, moon, stars, and zodiac signs are fixed, as it is stated: 'And God set them in the firmament [Rakia] of the heaven'"
"After this, on the second day, he placed the heaven over the whole world, and separated it from the other parts, and he determined it should stand by itself. He also placed a crystalline [firmament] round it, and put it together in a manner agreeable to the earth, and fitted it for giving moisture and rain"
Notes:
According to the Bible, we live under a solid, crystal-like dome that:
Ancient Near Eastern Context: This model aligns with ancient Near Eastern cosmologies featuring solid domes separating waters above from below. The biblical account shares this ancient structured, enclosed cosmic system.
Modern Cosmological Differences: The firmament model differs from modern astronomy in several aspects: modern science proposes no solid dome above Earth, no water reservoir in space, stars are massive distant objects rather than small lights that can fall, and the sun does not travel locally around a flat Earth. These represent differences between ancient and modern cosmological understanding.
Summary: This isn't modern astronomy - it's an ancient understanding of a solid dome over a flat Earth, with God's dwelling place above the water reservoir on top of the dome. The sun moves in its circuit within the dome, stars are small lights that can fall, and rain comes through windows in the solid ceiling.
The biblical text contains numerous passages consistently describing the firmament as a solid, architectural structure with functional features, not empty space. This cosmological model differs from modern cosmology in multiple aspects: the solid dome, the flat Earth, the local sun, and falling stars.
