3. The prophet returns to describe the grievousness of the calamity, in some particulars of it. Corn and cattle are the husbandman's staple commodities; now here he is deprived of both. (1.) The caterpillars have devoured the corn, v. 17. The garners, which they used to fill with corn, are laid desolate, and the barns broken down, because the corn has withered, and the owners think it not worth while to be at the charge of repairing them when they have nothing to put in them, nor are likely to have any thing; for the seed it rotten under the clods, either through too much rain or (which was the more common case in Canaan) for want of rain, or perhaps some insects under ground ate it up. When one crop fails the husband man hopes the next may make it up; but here they despair of that, the seedness being as bad as the harvest. (2.) The cattle perish too for want of grass (v. 18): How do the beasts groan! This the prophet takes notice of, that the people might be affected with it and lay to heart the judgment. The groans of the cattle should soften their hard and impenitent hearts. The herds of cattle, the large cattle (black cattle we call them), are perplexed; nay, even the flocks of sheep, which will live upon a common and be content with very short grass, are made desolate. See here the inferior creatures suffering for our transgression, and groaning under the double burden of being serviceable to the sin of man and subject to the curse of God for it. Cursed is the ground for thy sake.
