“If they refuse
To accept the cup
From your hand,
Then you shall say to them,
Thus says Yahweh of hosts.
‘You must drink!
See!
I am beginning
To bring disaster
On the city
That is called by my name.
How can you possibly
Avoid punishment?
You shall not go unpunished!
I am summoning a sword
Against all the inhabitants
Of the earth.’
Says Yahweh of hosts.”
Yahweh then tells Jeremiah what to say if they refuse to drink the cup of wrath from his hand. He told Jeremiah to say that they have to drink this cup. Yahweh was already preparing a disaster for the city that bore his name, Jerusalem. How could they possibly go unpunished? Yahweh was going to bring the sword to all the people living on earth. It would be a devastating end to the world.
