Most modern readers think of heaven as a single place — the destination at the end of life. But in ancient Jewish and early Christian cosmology, heaven was a layered structure. Multiple heavens, each with its own function and inhabitants, arranged in ascending order toward the throne of God.
Where does this idea come from? Primarily from the Book of Enoch.
Enoch's Journey
In 1 Enoch, the patriarch Enoch doesn't die. He is taken by God and transported on a journey through the heavens, guided by the archangel Uriel. What he sees forms the most detailed description of divine cosmology in any pre-Christian text:
The treasury of the winds. Enoch sees where snow, rain, dew, and the winds are stored — the mechanisms of weather governed by angelic custodians.
The prison of the fallen Watchers. A dark void where the angels who descended to earth are bound, awaiting final judgment. Their groaning fills the space around them.
The mountain of God. A towering structure at the center of the earth, around which the stars rotate, inaccessible to humans — the place where God will sit in judgment.
The throne room. Enoch is brought before the Great Glory itself — a vision of blinding light on a crystalline throne, surrounded by fire, angels, and the sound of praise that never ceases.
Why Paul Refers to the "Third Heaven"
In 2 Corinthians 12:2, Paul casually mentions being "caught up to the third heaven," as if his readers will understand the reference. They would have. The multi-heaven cosmology was widely known in the Second Temple Jewish world, largely through the Enochic tradition. Paul doesn't explain what the third heaven is because he doesn't have to.
The same framework appears in the Book of Revelation, in the letters of Ignatius, in later Jewish mystical texts like the Hekhalot literature. The entire architecture of apocalyptic cosmology flows from Enoch's journey.

The astronomical and cosmological sections of 1 Enoch are among the most fascinating and least-read parts of ancient scripture. The Book of Enoch — Collector's Edition presents the complete text, including the Astronomical Book (Chapters 72–82) — Enoch's detailed account of the movements of the sun, moon, and stars as he observed them from above the earth.
