Ambrose of Milan, on Exod 10:12

“And the Lord said to Moses: Stretch forth thy hand upon the land of Egypt unto the locust, that it may come upon it, and devour every herb that is left after the hail.”

“Even the locust, by divine grace, penetrates everywhere, and when it has filled the width of each region with its dense swarm, it first strikes without harm, and feeds on the barren land only after receiving the divine signal of permission. Indeed, just as we read in Exodus, it also acts as the celestial executor of righteous vengeance.”
