“All the inhabitants of the coastlands, are appalled at you,
And their kings are horribly afraid, their countenance is troubled,
The merchants among the people hiss at you, you have become terrors (a dreadful warning to men),
And you will be no more for ever.”
Their doom will shake the world. They will be for ever a dreadful warning to men and from it there is no escape. They will be a byword forever. The hissing of the merchants indicates not contempt but appalled awareness.
