Jeremiah 5:6 - Joseph Benson’s Commentary on the Old and New Testaments

Wherefore a lion, &c. Nebuchadnezzar and the Chaldean army are here pointed at under the metaphor of beasts of prey, of three kinds: being powerful, courageous, and violent as a lion; rapacious, greedy, and devouring as a wolf; and swift, lively, and active as a leopard. The word ערבוה, rendered evenings in the text, is translated deserts in the margin of our Bibles, which probably is the sense here intended. “And those wide and extensive plains, or unenclosed commons, seem to be meant, which were used only for sheep-walks and pasturage, and were, of course, most likely to be infested with wolves.” Blaney.
