יֶרַח
Jerach, an Arabian patriarch
Definition
Yerach (Jerah) is a proper name referring to an Arabian patriarch listed in the genealogies of Genesis and 1 Chronicles. He is identified as a descendant of Shem through Joktan, placing him among the early Arabian tribes (Genesis 10:26, 1 Chronicles 1:20). The name itself is identical to the common Hebrew noun for 'moon' or 'month' (יֶרַח, H3391), which may indicate a cultural or ancestral connection to lunar worship or timekeeping. As a personal name, it serves primarily to denote an individual within the Table of Nations, with no other narrative or descriptive details provided in the biblical text.
Biblical Usage
The word Yerach is used exclusively as a proper name in two parallel genealogical lists: Genesis 10:26 and 1 Chronicles 1:20. In both instances, it appears in the lineage of Joktan, a son of Eber, within the Table of Nations. This usage is purely onomastic, serving to catalog an ancestral figure among the Semitic peoples. No other contexts, narratives, or descriptive passages involve this name.
Etymology
Yerach is derived from the same root as the common Hebrew noun יֶרַח (yerach, H3391), meaning 'month' or 'moon.' The name is therefore a direct borrowing of this lunar term, likely reflecting the cultural significance of the moon in ancient Semitic societies, particularly among Arabian tribes. Cognates appear in other Semitic languages, such as Arabic 'warḫ' (month) and Aramaic 'yarḥā’' (moon). As a personal name, it exemplifies the common ancient practice of using celestial bodies or units of time for nomenclature.
Semantic Range
While Yerach itself is not theologically loaded, its inclusion in the Genesis 10 genealogy is significant. It affirms the biblical theme of God's sovereignty over all nations, tracing the origins of peoples back to a common ancestry after the Flood. Understanding that this patriarch's name means 'moon' can subtly remind readers of the ancient cultural context where celestial bodies were often venerated, contrasting with the biblical mandate to worship the Creator alone. His placement in the line of Shem also connects him to the lineage through which God's redemptive promises would eventually flow.
In the ancient Near East, names were often meaningful and descriptive. Using 'moon' (Yerach) as a personal name likely reflects the importance of lunar cycles for timekeeping, agriculture, and religious observance in pre-Islamic Arabian culture. Some Arabian tribes were known for moon worship, and names like Jerah may hint at such associations, though the biblical text makes no explicit comment on this. The genealogical listing places him among the 'Joktanite' Arabs, a group associated with the Arabian Peninsula.
yareach (יָרֵחַ, H3394) — The more common term for 'moon,' often used in poetic and prophetic texts, whereas Yerach (H3392) is primarily a proper name or denotes 'month.'

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.
