What does Jeremiah 4:30 mean?

And you, devastated city, what are you doing? Why dress up in fancy clothes, put on jewelry, and paint your eyes? You’re just making yourself look good for nothing. Your lovers hate you now—they’re out to kill you. Jeremiah 4:30 - Modern Text Bible

(Jerusalem’s attempts to save herself with outward beauty or alliances are pointless; those she trusted have turned against her.)
