Jeremiah 5:6

Nebuchadnezzar and the Chaldean army from Syria and Libanus, woody places, are here pointed at under the metaphor of beasts of prey of three kinds; the malignity that is proper to each of these creatures shall be put forth in this Babylonian army, compared, for instance, to a lion, Jeremiah 4:7 which notes his great power, courage, pride, and insulting over his prey. A wolf, for their greediness and unsatiableness; one wolf will destroy abundance of sheep; and said to be the wolf of the evenings, or deserts, or plains, they being the usual haunts of the wolf; or evenings, because then they are observed to be most ravenous, Habakkuk 1:8, possibly because lying most part of the day in their dens for fear of the huntsmen, want of prey enrageth their hunger at night; and because of this greediness to devour, the judges among themselves are said to be evening wolves, described Zephaniah 3:3, They gnaw not the bones till the morrow, either through hunger or rage. A leopard; the Chaldean army compared to a leopard, not for its speed only, but especially for its vigilancy and subtlety; they will be so vigilant, that scarce any shall escape, according to Jeremiah 4:16. Increased, Heb. strong: here is the reason why God would bring such a devastation upon them, because they did, as it were, strengthen themselves in the multitude of their rebellions against him.
