רֶבַע
a fourth (part or side)
Definition
The Hebrew noun רֶבַע (rebaʻ) fundamentally means 'a fourth' or 'quarter,' referring to one of four equal parts. In the Bible, it most literally denotes a quarter of a standard measure, such as a fourth of a hin of oil (Exodus 29:40). It also describes the four sides or quadrants of an object, particularly in the visionary descriptions of Ezekiel, where it refers to the four sides of the cherubim's wheels (Ezekiel 1:17) and the four divisions of the altar (Ezekiel 43:16). Thus, the word encompasses both a fractional division and a spatial, directional concept of fourfold symmetry.
Biblical Usage
רֶבַע is used seven times in the Old Testament, primarily in two contexts. First, it appears in cultic or practical measurements, specifying a quarter of a liquid measure (Exodus 29:40; 1 Samuel 9:8). Second, and more prominently, it is used in Ezekiel's visions (five occurrences) to describe the fourfold structure of heavenly beings and sacred objects—specifically, the four sides of the cherubim's wheels (Ezekiel 1:8, 1:17, 10:11) and the four square divisions of the altar (Ezekiel 43:16, 43:17). This pattern shows a shift from mundane measurement to visionary, symbolic architecture.
Etymology
רֶבַע is a noun derived from the root רָבַע (H7251), meaning 'to lie down' or 'to square.' The connection likely stems from the idea of something being divided or arranged into four parts, akin to the four legs of an animal lying down or the four corners of a square. Cognates in other Semitic languages also relate to the number four, reinforcing its fundamental association with quadruple division.
Semantic Range
In Ezekiel's visions, רֶבַע contributes to the profound symbolism of divine order and completeness. The four sides of the cherubim's wheels (Ezekiel 1:17-18) emphasize God's omnipresence and mobility—His glory moves perfectly in all directions. Similarly, the altar's foursquare design (Ezekiel 43:16) signifies sacred perfection and stability, pointing to God's holy and unshakeable nature. Understanding this term enriches the reader's appreciation of how biblical imagery uses numerical symmetry to convey theological truths about God's character and the structure of His heavenly realm.
In ancient Israelite culture, standard measures like the hin were essential for trade and religious rituals. A 'fourth part' (רֶבַע) was a practical subdivision for precise offerings, as seen in Exodus 29:40. The concept of four sides or quadrants also reflected a common ancient Near Eastern understanding of the world's four cardinal directions, which Ezekiel's visions adapt to depict cosmic and divine order. This differs from a modern, purely abstract understanding of 'a quarter,' as it carried concrete ritual and spatial significance.
רְבִיעִי (reviʻiy, H7243) — the ordinal number 'fourth,' describing sequence rather than a part or side. מְרֻבָּע (merubaʻ, H7243) — an adjective meaning 'square' or 'foursquare,' focusing on the shape rather than the division.

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.
