17So I took the cup from the Lord’s hand and made all the nations to whom he sent me drink it: 18Jerusalem and the towns of Judah, its kings and officials, to make them a ruin and an object of horror and scorn, a curse c —as they are today; 19Pharaoh king of Egypt, his attendants, his officials and all his people, 20and all the foreign people there; all the kings of Uz; all the kings of the Philistines (those of Ashkelon, Gaza, Ekron, and the people left at Ashdod); 21Edom, Moab and Ammon; 22 all the kings of Tyre and Sidon; the kings of the coastlands across the sea; 23Dedan, Tema, Buz and all who are in distant places; 24 all the kings of Arabia and all the kings of the foreign people who live in the wilderness; 25all the kings of Zimri, Elam and Media; 26and all the kings of the north, near and far, one after the other—all the kingdoms on the face of the earth. And after all of them, the king of Sheshak will drink it too.
Logistically speaking, this was impossible for Jeremiah to literally accomplish all these running around.
Does Jeremiah literally visit the nations and hand them the cup of God's wrath?
No. The whole passage was partly a vision and partly symbolic.
