What does Jeremiah 21:12 mean?

This is what the Lord says: 'Every morning, make sure you do what's right. Rescue people from those who are cheating or hurting them. If you don't, my anger will burn like a fire that can't be put out, because of all the evil you've done.' Jeremiah 21:12 - Modern Text Bible

(God urges the leaders to act justly and protect the vulnerable, warning that his anger will be unstoppable if they don't.)
