Arm

arm ( זרוע , zerōa‛ , אזרוע , 'ezrōa‛ , דּרע , derā‛  ; βραχίων , brachı́ōn  ; חצן , ḥōcen , כּתף , kāthēph ): The usual form is zerōa‛ from the root zāra‛ , "to spread." The arm may be "stretched out." 'Ezrōa‛ is this form with prosthetic 'ālēph ( Job 31:22; Jeremiah 32:21 ), and derā‛ is the Aramaic form. Ḥōcen is really "bosom," thus the Revised Version (British and American) ( Isaiah 49:22 ); and kāthēph is "shoulder," thus the Revised Version (British and American) ( Job 31:22 ). Compare χείρ , cheı́r , also, in Acts 11:21 .

Figurative: The arm denotes influence, power, means of support or conquest. The arms of Moab ( Jeremiah 48:25 ) and of Pharaoh ( Ezekiel 30:21 ) are broken. The arm of Eli and the arm of his father's house are to be cut off ( 1 Samuel 2:31 ). Because the arm wielded the sword it signified "oppression" ( Job 35:9 ). The arms are the means of support, therefore to refuse to aid the fatherless is to break their arms ( Job 22:9 ).

Applied anthropomorphically to God, the arm denotes also His power, power to deliver, support, conquer. His "outstretched arm" delivered Israel from Egypt ( Exodus 6:6; Deuteronomy 4:34 , etc.). They support: "Underneath are the everlasting arms" ( Deuteronomy 33:27 ). His arm protects ( Isaiah 40:11 ). Yahweh is sometimes likened to a warrior and smites with His arm ( Psalm 89:10; Isaiah 63:5; Jeremiah 21:5 ). The arm of Yahweh is holy ( Psalm 98:1; Isaiah 52:10 ). Many other passages of Scripture might be quoted showing how the power of God to redeem, judge, protect, punish is expressed by the idea of "the arm of Yahweh."
