רָקִיעַ
properly, an expanse, i.e. the firmament or (apparently) visible arch of the sky
Definition
The Hebrew noun רָקִיעַ (rāqîaʿ) refers to a solid, expansive structure, most often translated as 'firmament' or 'expanse.' Its primary biblical meaning is the dome-like sky that separates the 'waters above' from the 'waters below' (Genesis 1:6-8). This expanse is the location for celestial bodies like the sun, moon, and stars (Genesis 1:14-17) and is also the space where birds fly (Genesis 1:20). In poetic contexts, such as Psalm 19:1 and Psalm 150:1, it is synonymous with the heavens, declaring God's glory.
Biblical Usage
This word is used exclusively in cosmological and poetic contexts. It appears 15 times, with 9 occurrences in Genesis 1, defining the structure of creation. The remaining uses are in poetic books: Ezekiel (1:22-26, 10:1) and the Psalms (19:1, 150:1). In Genesis, it is a key architectural feature of the ordered world. In Ezekiel, it forms part of the prophet's visionary throne-chariot. In the Psalms, it is part of the created order that praises God.
Etymology
Derived from the root רָקַע (rāqaʿ, H7554), meaning 'to beat out, spread out, or hammer,' as a metalsmith would hammer a thin sheet of metal (cf. Exodus 39:3). Thus, רָקִיעַ conceptually means something that has been stretched out or extended, like a vast, hammered-out dome. This root informs the ancient understanding of the sky as a solid, manufactured structure.
Semantic Range
This word is crucial for understanding the ancient Hebrew cosmology, which depicted a structured, ordered universe created by God's command. It highlights God's sovereignty as the divine architect who establishes boundaries within creation. Recognizing this 'expanse' as a tangible part of the biblical world picture enriches reading by showing how the authors visualized God's creative power and the stability of the cosmos under His authority.
In the ancient Near Eastern worldview, the sky was often perceived as a solid dome or firmament holding back celestial waters. The biblical use of רָקִיעַ shares this cultural concept but uniquely attributes its existence solely to the command of Yahweh, not as a result of conflict with other gods. This differs from a modern scientific view of the atmosphere as gaseous.
שָׁמַיִם (shāmayim, H8064) — A broader term for 'heavens' or 'sky,' encompassing all that is above the earth, including the רָקִיעַ. חוּג (ḥûg, H2329) — Used in Job 22:14 for the 'vault' or 'circle' of the heavens, emphasizing its curved, encompassing nature.

How this works
Hebrew definitions are from Brown-Driver-Briggs (1906) and Strong's Exhaustive Concordance (1890), both public domain. BDB was groundbreaking for its era but reflects 19th-century assumptions about Semitic etymology. Modern scholarship (HALOT, DCH) has revised many entries. Use these definitions as a starting point for exploration, not as the final word on a term's meaning in context.
