In that day, Yahweh with his hard and great and strong sword will punish leviathan, the fleeing serpent, and leviathan the twisted serpent; and he will kill the dragon that is in the sea.

Echo3
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
Yahweh punishes Leviathan, the fleeing/twisting serpent, the dragon (LXX drakonta) that is in the sea — a chief OT source for 'great red dragon' (drakōn). Recurrence with 12:9; combat-myth backdrop.
Medium confidenceYHWH 'shall punish leviathan the piercing serpent... and he shall slay the dragon (LXX drakonta) that is in the sea.' The dragon/serpent chaos-beast slain or subdued; 'serpent' + 'dragon' pairing parallels Rev 20:2's stacked epithets. Hays satisfaction: same eschatological defeat of the chaos-serpent.
Medium confidenceLeviathan 'the dragon that is in the sea' slain by Yahweh — keeps the dragon = sea-serpent identification active as the serpent spews a river; faint reinforcement.
