(3.) Sometimes the fruits of their ground were eaten up by caterpillars, or blasted with mildew, v. 9. Heaven and earth are armed against those who have made God their enemy. When God pleased, that is, when he was displeased, [1.] They suffered by a malignant air, the influence of which, either too hot or too cold, blasted their fruits, with a force that could be neither discerned nor resisted, and against which there was no defence. [2.] They suffered by malignant animals. Their vineyards and gardens yielded their increase in great abundance, so did their fig-trees and olive-trees; but the palmer-worm devoured them before the fruits were ripe, and fit to be gathered in. This was either the same judgment with that which we read of Joel i. 4-6, or a less judgment of the same nature, sent before to give warning of that. But they did not take warning: Yet have you not returned unto me.
