This chapter prophecies Yahweh's punishment on Judah. This should bring Judah to repentance, but it does not. It is also intended to make the nations fear the power of Yahweh and make them desire to worship him. The prophecy revealed to Jeremiah is recorded in 3:19-4:3. Despite covering more than one chapter, this should be seen as one unit. The ULB sets poetry (4:1-9) farther to the right than the rest of the text to show that it is poetry.
