In the wake of the Babylonian destruction of Jerusalem in 586 BC, the prophet Jeremiah, who had long counseled his fellow Judeans to yield to Babylon’s might, made the surprising decision to leave Judah with a departing caravan headed for Egypt, never to return to his homeland (Jeremiah 43). We know little about Jeremiah’s reasons for leaving, and the Bible provides only a faint glimpse of his final years spent preaching to Judean exiles in Egypt. But thanks to new archaeological and geological evidence from Egypt’s eastern Nile Delta, we are now able to identify the precise route that Jeremiah and his fellow Judean travelers took to reach Egypt
