1:1-7 The most aged could not remember such calamities as were about to take place. Armies of insects were coming upon the land to eat the fruits of it. It is expressed so as to apply also to the destruction of the country by a foreign enemy, and seems to refer to the devastations of the Chaldeans. God is Lord of hosts, has every creature at his command, and, when he pleases, can humble and mortify a proud, rebellious people, by the weakest and most contemptible creatures. It is just with God to take away the comforts which are abused to luxury and excess; and the more men place their happiness in the gratifications of sense, the more severe temporal afflictions are upon them. The more earthly delights we make needful to satisfy us, the more we expose ourselves to trouble.

4. This verse states the subject on which he afterwards expands. Four species or stages of locusts, rather than four different insects, are meant (compare Le 11:22). Literally, (1) the gnawing locust; (2) the swarming locust; (3) the licking locust; (4) the consuming locust; forming a climax to the most destructive kind. The last is often three inches long, and the two antennæ, each an inch long. The two hinder of its six feet are larger than the rest, adapting it for leaping. The first "kind" is that of the locust, having just emerged from the egg in spring, and without wings. The second is when at the end of spring, still in their first skin, the locusts put forth little ones without legs or wings. The third, when after their third casting of the old skin, they get small wings, which enable them to leap the better, but not to fly. Being unable to go away till their wings are matured, they devour all before them, grass, shrubs, and bark of trees: translated "rough caterpillars" (Jer 51:27). The fourth kind, the matured winged locusts (see on [1129]Na 3:16). In Joe 2:25 they are enumerated in the reverse order, where the restoration of the devastations caused by them is promised. The Hebrews make the first species refer to Assyria and Babylon; the second species, to Medo-Persia; the third, to Greco-Macedonia and Antiochus Epiphanes; the fourth, to the Romans. Though the primary reference be to literal locusts, the Holy Spirit doubtless had in view the successive empires which assailed Judea, each worse than its predecessor, Rome being the climax.
