What does Jeremiah 48:11 mean?

Moab has had it easy for a long time, never shaken up or forced to move. He’s settled in, like wine left undisturbed on its dregs, never poured from one jar to another. That’s why his taste hasn’t changed and his scent is still the same. Jeremiah 48:11 - Modern Text Bible

(Moab is described as complacent and unchanged, like wine that’s never been disturbed. This is a metaphor for a nation that’s grown comfortable and self-satisfied because it hasn’t faced hardship or exile.)
