Arm

ARM. Used as a figure for personal, active power. Thus the Lord lays “bare his holy arm” (Isa.52.10), rather as we might say of someone about to undertake some task, “he rolled up his sleeves.” The Lord’s arm (Isa.53.1) is figurative of his personal intervention. In particular the figure of the “arm” looks back to what the Lord did at the Exodus (Exod.6.6; Deut.4.34; Deut.5.15; Isa.51.9-Isa.51.11).
