The dragon in Revelation 12:3 recalls Old Testament imagery of Leviathan, the primordial sea monster that symbolizes chaos, evil, and the enemies of God. In texts such as Psalm 74:13–14, Isaiah 27:1, and Ezekiel 29:3, Leviathan is portrayed as a monstrous creature subdued by God, representing His power to conquer cosmic and political forces of disorder. Revelation draws upon this imagery to depict the dragon as the ultimate cosmic adversary—an embodiment of Satanic rebellion and opposition to God’s kingdom.
