Arm

Arm, in Scripture, is both the literal limb and one of the Bible's main images for strength and power at work — human or divine — so that "the arm of Yahweh" regularly stands for God acting in the world. In ordinary usage the Hebrew word zerowaʿ means the physical arm, as when Isaiah pictures a shepherd gathering lambs "in his arm" (Isaiah 40:11). As metaphor it carries the sense of force and deliverance: "You have a mighty arm. Your hand is strong, and your right hand is exalted" (Psalms 89:13), and "His right hand and his holy arm have worked salvation for him" (Psalms 98:1). The language is concrete rather than abstract; the arm is God's own power considered as exercised, not merely possessed.

Established usage ties the phrase "outstretched arm" (zerowaʿ netuyah) closely to the exodus. Deuteronomy 4:34 lists it among the means by which God took a nation for himself — "by a mighty hand, by an outstretched arm, and by great terrors" — and Jeremiah applies the same pair of images to creation and to God's free disposal of the earth: "I have made the earth, the men, and the animals… by my great power and by my outstretched arm" (Jeremiah 27:5; compare Jeremiah 32:17). Isaiah uses the image for public, universal revelation: "Yahweh has made his holy arm bare in the eyes of all the nations. All the ends of the earth have seen the salvation of our God" (Isaiah 52:10), and then for the message that is not believed: "Who has believed our message? To whom has Yahweh's arm been revealed?" (Isaiah 53:1). Isaiah 51:9 addresses the arm directly — "Awake, awake, put on strength, arm of Yahweh!" — recalling the defeat of Rahab and the monster, names drawn from ancient chaos imagery. The same arm is not only martial: "Underneath are the everlasting arms" (Deuteronomy 33:27), and the arm that rules also gathers lambs and carries them (Isaiah 40:11). In the Greek of the New Testament the word is brachiōn, and Luke 1:51 echoes the Septuagint's exodus phrasing: "He has shown strength with his arm. He has scattered the proud in the imagination of their hearts."

Traditions read the image differently. Most Christian interpreters, following the New Testament's own citation of Isaiah 53:1 in John 12:38, take "the arm of the Lord revealed" as pointing to Christ and the gospel, and patristic writers often treated the arm as the Son or Word, God's power going out from him; some later Jewish and Christian readers have resisted any suggestion of a distinct agent, hearing in "arm of Yahweh" only a vivid idiom for God's own action, and Isaiah 51:9 as poetic address to God himself rather than to a personified power. Devotional reading has also pressed the shepherd side of the image, taking "everlasting arms" (Deuteronomy 33:27) as a picture of sustaining support, while others emphasize the martial, exodus sense of a God who fights for his people. These are differences of emphasis and of theological grammar rather than disputes over what the texts say.
