Joel 1:6 - Joseph Benson’s Commentary on the Old and New Testaments

For a nation is come up upon my land Insects are described as a nation or people marching in order under their leaders, both by sacred and profane writers, because of their power to do mischief, and their being irresistible by human strength or art. Whose teeth are the teeth of a lion They devour every thing that comes in their way, and there is no possibility of rescuing it from them. Pliny and other writers tell us, that they will not only destroy the leaves and fruits of the trees on which they fasten, but will even devour the very bark and stock thereof.
