In that day, at the time when God's judgments will be carried out upon the world, the Lord with His sore and great and strong sword, His well-tempered, powerful, and irresistible weapon, shall punish leviathan, the piercing serpent, the fleeing dragon, even leviathan, that crooked serpent, whose mighty coils threaten to crush everything they enfold; and He shall slay the dragon that is in the sea, the reference being to the three great world-powers, Assyria, along the Tigris, Babylonia, along the Euphrates, and Egypt, representing all the forces which are hostile to the Lord and His people.
