זְרוֹעַ
the arm (as stretched out), or (of animals) the foreleg; figuratively, force
Definition
The Hebrew word זְרוֹעַ primarily means 'arm' or 'foreleg,' referring literally to the human limb (e.g., Numbers 6:19) or an animal's leg. Figuratively, it powerfully denotes strength, might, or military force, as seen when nations are defeated by a 'mighty arm' (Deuteronomy 4:34). Most significantly, it is a key metaphor for God's saving power and active intervention in history, especially in delivering Israel from Egypt with an 'outstretched arm' (Exodus 6:6). In poetic texts, it can symbolize God's enduring strength and protection, as in the 'everlasting arms' of Deuteronomy 33:27.
Biblical Usage
זְרוֹעַ appears 84 times, predominantly in poetic, prophetic, and historical books. Its usage is highly thematic: in the Pentateuch and historical books, it frequently describes God's powerful, saving acts, especially the Exodus (Exodus 15:16, Deuteronomy 7:19). In poetic books like Psalms and Isaiah, it celebrates God's ongoing strength and rule (Psalm 44:3, Isaiah 40:10). It also describes human or national military power, often in contexts of judgment (Ezekiel 30:21). A unique sacrificial usage is found in the wave offering of the ram's 'shoulder' (זְרוֹעַ) in Numbers 6:19.
Etymology
Derived from the root זָרַע (zāraʿ, H2232), meaning 'to sow' or 'to scatter.' The connection likely stems from the arm's action in sowing seed—a casting forth or stretching out. This root sense beautifully informs the word's figurative use for God's 'outstretched' arm in deliverance. Cognates in other Semitic languages, like Ugaritic *drʿ*, also mean 'arm' and 'power,' confirming the ancient association of the limb with strength.
Semantic Range
זְרוֹעַ is a profoundly theological word, central to understanding God's character and acts. It encapsulates the doctrine of God's mighty salvation, portraying Him not as a distant deity but as an active, powerful deliverer. The 'outstretched arm' becomes a covenant symbol of redemption, most famously in the Exodus. This metaphor is later expanded by the prophets to describe God's future salvation (Isaiah 52:10) and is foundational for New Testament concepts of Christ as the manifestation of God's saving power (Luke 1:51). Understanding this Hebrew term enriches reading by grounding abstract ideas of 'salvation' and 'power' in the concrete, historical action of God.
In ancient Near Eastern culture, the arm was a universal symbol of strength, authority, and capacity for action. A deity's 'arm' represented his active power in the world, a concept also found in Egyptian and Mesopotamian texts. For Israel, this familiar cultural symbol was uniquely applied to Yahweh, distinguishing Him as a God who acts decisively in history for His people, unlike idols who 'have hands, but cannot feel' (Psalm 115:7). The 'outstretched arm' specifically evoked the image of a warrior-king or a powerful benefactor intervening on behalf of the weak.
יָד (yāḏ, H3027) — 'hand'; more general, often denotes possession, action, or power. חַיִל (ḥayil, H2428) — 'strength, army, wealth'; denotes capacity, resources, or military might more broadly. כֹּחַ (kōaḥ, H3581) — 'strength, power'; emphasizes inherent force or ability, less often personified as a limb. עֹז (ʿōz, H5797) — 'might, strength'; often used in parallel with זְרוֹעַ, emphasizing majestic power.

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.
