רָקִיעַ (ra.qi.a)

The Hebrew noun raqia refers to an extended, flat surface or expanse. In the creation accounts of Genesis and later prophetic literature like Daniel, it describes the vault of heaven that separates the waters below from those above. The word carries a sense of solidity, reflecting the ancient understanding of the sky as a physical structure rather than empty space.

This meaning stems from the root verb raqa, which means to beat or spread out thin, like metal foil. The sources emphasize that raqia was viewed as a firmament supporting the celestial waters, a concept central to the cosmology of the time. Translators often render it "firmament," though this archaic term can obscure the idea of a broad, stretched-out surface.

Its usage highlights how biblical authors described the natural world using the physical realities they observed. The raqia serves as a structural element in the narrative, holding back the waters and defining the boundary between earth and sky. This concrete imagery grounds the theological claim that God ordered the cosmos with intentionality.
