Daniel finished up this prayer with a demand that the Lord God act right away and not delay. He wanted God to see and listen to his prayers and supplications, not because of their righteousness, but for the sake of his name and his great mercy. He wanted God to see their desolated sanctuary. He wanted God to see what was happening to the city that bore his name. He wanted God to see, hear, listen, forgive, act, and not delay.
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.
