יָרֵחַ
the moon
Definition
The Hebrew word יָרֵחַ specifically refers to the moon as a celestial body. It denotes the physical moon in the sky, often in contrast to the sun (Genesis 37:9). In several passages, it is listed among the heavenly host, which were objects of forbidden worship (Deuteronomy 4:19, 2 Kings 23:5). The word can also be used poetically to symbolize something pale or wan, as in the description of the moon being 'not bright' in Job 25:5. It is distinct from the word for 'month' (חֹדֶשׁ), though both are related to lunar cycles.
Biblical Usage
The word is used 26 times, primarily in narrative and legal contexts. It appears in key stories like Joseph's dream (Genesis 37:9) and Joshua's long day (Joshua 10:12-13). A major pattern is its use in warnings against idolatry, where worshiping the moon is explicitly prohibited (Deuteronomy 17:3). It is also found in poetic books like Job (Job 25:5, 31:26). The usage is consistently literal, referring to the astronomical object, never as a metaphor for time.
Etymology
Derived from the same root as יֶרַח (H3391), which means 'month' or 'moon.' Both words are connected to the lunar cycle. The root is likely related to a verb meaning 'to be pale' or 'to be white,' reflecting the moon's appearance. Cognates exist in other Semitic languages, like Ugaritic 'yrḫ' and Arabic 'warḫ,' both meaning 'month,' showing the deep cultural link between the moon and the calendar.
Semantic Range
This word is theologically significant because the moon, as part of God's creation (Genesis 1:16), was often misappropriated for idolatrous worship in the ancient Near East. Biblical texts sternly forbid worshiping the יָרֵחַ (Deuteronomy 4:19), affirming that only the Creator, not the creation, is to be revered. Understanding this Hebrew term highlights the constant biblical tension between recognizing God's handiwork in the heavens and the temptation to deify those very objects, a key theme in Israel's covenant faithfulness.
In the ancient Near East, the moon was frequently personified and worshiped as a deity (e.g., Sin in Mesopotamia). The biblical use of יָרֵחַ deliberately demythologizes it, presenting it solely as a created object under God's command (Joshua 10:12). This stood in stark contrast to surrounding cultures. The moon also played a practical role in marking time for agricultural and religious festivals, though the Hebrew calendar later became more solar-regulated.
לְבָנָה (lᵉḇānâ, H3842) — A poetic synonym for 'moon,' emphasizing its whiteness. Used in Song of Solomon 6:10. חֹדֶשׁ (ḥōḏeš, H2320) — Means 'new moon' or 'month,' focusing on the lunar cycle as a measure of time, not the physical object.

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.
