To those who argue that all gods are equal, Isaiah describes the fate of those same (other) gods.
On the day God judges the nations …
Isaiah 24:21-23 In that day the Lord will punish the gods in the heavens and the proud rulers of the nations on earth.
They will be rounded up and put in prison.
They will be shut up in prison
and will finally be punished.
Then the glory of the moon will wane,
and the brightness of the sun will fade,
for the Lord of Heaven’s Armies will rule on Mount Zion.
He will rule in great glory in Jerusalem,
in the sight of all the leaders of his people.
And in case there’s any doubt about the fate of these false gods:
Isaiah 27:1 In that day the Lord will take his terrible, swift sword and punish Leviathan, the swiftly moving serpent, the coiling, writhing serpent. He will kill the dragon of the sea.
