Jer Jeremiah, chapter Book of Jeremiah, chapter 13
Take the loincloth that you bought and put on, and go immediately to the River Perath13:4. The River Perath in Hebrew is usually translated as the Euphrates. However, this would mean Jeremiah going on two round trips of some 700 miles each. Some have suggested that the river in question was one with a similar name located near to Anathoth. Insofar as this is an acted parable it seems likely that others were supposed to see what happened and understand what it meant, so the actual Euphrates seems an unlikely location. However, the symbolic aspect must be included since the invaders would be coming from Babylon on the Euphrates. and hide it there in a hole among the rocks.
