And the LORD said unto Moses,
Stretch out your hand over the land of Egypt for the locusts, that they may come up upon the land of Egypt, and eat every herb of the land, even all that the hail has left.
Read Chapter 10
Ambrose of Milan
Divine grace has penetrated even into the life of a locust. When a locust swarms over and takes possession of some extent of land, no harm at first is done to the land. Nothing is devoured by these unfriendly invaders except when a sign from heaven has been received. A passage in Exodus provides an example of this. There the locust as minister of divine vengeance inflicts punishment for an offense against heaven. .
