Charles Ellicott Commentary Jeremiah 4:25

"I beheld, and, lo, there was no man, and all the birds of the heavens were fled." — Jeremiah 4:25 (ASV)

There was no man. —To chaos and darkness and the earthquake was added the horrible sense of solitude. Not man only, but the creatures that seemed least open to man’s attack, had fled . The same thought reappears in Jeremiah 9:10.
