What does Jeremiah 40:9 mean?

As for me, I'm staying here at Mizpah to represent you before the Babylonians who come to us. But you—gather wine, summer fruit, and oil, store them in your containers, and settle in the towns you've taken over.' Jeremiah 40:9 - Modern Text Bible

(Gedaliah assures them he'll handle relations with Babylon, while they should focus on rebuilding their lives and gathering supplies.)
