Significance: Isaiah 51:9 calls on the "arm of the LORD" to "awake" and recalls when it "cut Rahab (רַהַב, Rahav) to pieces" and "pierced the dragon (תַּנִּין, tannin)," using mythological sea-monster language for the exodus victory. Isaiah 27:1 similarly promises that God will punish "Leviathan the fleeing serpent (נָחָשׁ, nachash), Leviathan the coiling serpent," and "slay the dragon (תַּנִּין, tannin) in the sea." Both passages use the same dragon/chaos-monster vocabulary (tannin) to describe God's victory over hostile powers. Isaiah 51:9 applies this to the historical exodus; Isaiah 27:1 projects it eschatologically onto the final defeat of evil. The shared imagery creates a trajectory from past deliverance through present hope to future cosmic victory.
