What does Jeremiah 42:9 mean?

He said, 'This is what the Lord, the God of Israel, says: If you stay here in this land, I'll build you up and not tear you down. I'll plant you and not uproot you, because I'm not angry with you anymore.' Jeremiah 42:9 - Modern Text Bible

(God promises stability and restoration if they remain in Judah, assuring them that His anger has passed.)
