STRONGS NT 1023: βραχίων

βραχίων, βραχίονος, (from Homer down), the arm: the βραχίων of God is spoken of Hebraistically for the might, the power of God, Luke 1:51 (cf. Deuteronomy 4:34; Deuteronomy 5:15; Deuteronomy 26:8); John 12:38 (Isaiah 53:1); Acts 13:17.

Topical Lexicon
Root Meaning and Old Testament Background

Throughout the Hebrew Scriptures the “arm” signifies effective strength, especially Yahweh’s sovereign ability to redeem, judge, and sustain His covenant people (Exodus 6:6; Deuteronomy 4:34; Psalm 98:1; Isaiah 52:10). The Septuagint regularly employs βραχίων to translate the Hebrew zᵊrôaʿ, so New Testament readers inherited a rich theological backdrop: the “arm of the LORD” embodies both His might and His mercy, unfolding redemptive history from the Exodus to the promised Messianic deliverance.

Occurrences in the New Testament

1. John 12:38—John cites Isaiah 53:1, “Lord, who has believed our message? And to whom has the arm of the Lord been revealed?”. Here Christ Himself is the unveiled Arm, and unbelief in Him fulfills prophecy.
2. Luke 1:51—Mary exults, “He has performed mighty deeds with His arm; He has scattered those who are proud in the thoughts of their hearts”. The birth of Jesus inaugurates God’s long-awaited reversal of human pride and elevation of humble faith.
3. Acts 13:17—Paul reminds the synagogue in Pisidian Antioch that God “led them out of that land with an uplifted arm”, grounding the gospel in the historical Exodus as a typological precursor to deliverance through Christ.

Arm as Metaphor for Divine Power and Salvation

In each occurrence βραχίων portrays decisive, saving intervention:
• Deliverance from oppression (Acts 13).
• Overthrow of worldly arrogance (Luke 1).
• Revelation of the suffering yet victorious Messiah (John 12).

The arm motif fuses God’s omnipotence with covenant fidelity, showing that true power is exercised for salvation and not merely domination.

Christological Fulfillment

Isaiah’s “arm of the LORD” materializes in Jesus. His miracles, atoning death, and resurrection constitute the climactic “mighty deed.” When John couples Isaiah 53 with unbelief, he underscores that rejection of Christ is rejection of God’s redemptive arm. Conversely, Mary’s Magnificat recognizes the Incarnation as that same arm now active within history. The early church’s preaching (Acts 13) interprets the Exodus and all ensuing acts of power as anticipatory shadows of Christ’s definitive redemption.

Soteriological and Missional Implications

Paul’s rehearsal of Israel’s account situates the gospel within God’s ongoing demonstration of strength. The arm that once liberated from Pharaoh now frees from sin and death. Proclaimers of the gospel therefore call hearers to trust not in human might but in the revealed Arm—Jesus Christ crucified and risen. Unbelief is shown to be moral, not intellectual, for the arm has already been “revealed.”

Pastoral and Devotional Application

Believers draw assurance from the Arm’s unwavering power:
• Comfort amid weakness—His arm accomplishes what human hands cannot (Isaiah 59:1; John 10:28).
• Humility—Mary’s song warns that pride invites scattering, whereas humility receives exaltation.
• Perseverance in mission—confidence that the same arm that opened the Red Sea can open hardened hearts.

Historical Usage in Early Church and Worship

Early Christian writers interpreted the “arm” christologically (e.g., Justin Martyr, Irenaeus), emphasizing that divine power is self-revealed in the incarnate Son. Baptismal liturgies celebrated deliverance “by the strong and outstretched arm,” linking water crossing themes to union with Christ. Hymns such as “O Arm of the Lord, awake” continued this devotional lineage.

Eschatological Hope

Prophets foresaw a day when “all the ends of the earth will see the salvation of our God” (Isaiah 52:10). Revelation anticipates consummation when every opposing power is subdued by the Lamb’s authority, the ultimate display of the Arm’s might. Thus βραχίων invites believers to await the final victory with steadfast hope.

Key Theological Themes

Power with purpose; covenant faithfulness; reversal of human pride; Christ as divine agent; continuity between Exodus and Gospel; assurance for mission and worship.

Related Old Testament Passages

Exodus 6:6; Deuteronomy 4:34; Psalm 44:3; Psalm 98:1; Isaiah 40:10-11; Isaiah 52:10; Isaiah 53:1; Jeremiah 32:17.

Summary

βραχίων focuses attention on God’s mighty, saving action, culminating in Jesus Christ. From the Exodus to the empty tomb, Scripture presents one consistent narrative: the Arm of the LORD is stretched out to redeem, humble the proud, and secure an everlasting people for His glory.
