What does Jeremiah 50:44 mean?

Just like a lion coming up from the thick brush along the Jordan to a safe pasture, I’ll suddenly chase Babylon out of her land. I’ll choose someone to rule over her. Who is like Me? Who can challenge Me? What leader can stand up to Me? Jeremiah 50:44 - Modern Text Bible

(God compares Himself to a lion driving Babylon out of her land, making it clear that no one can oppose His will or stop His plans.)
