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."
