Exodus 10:5

They shall cover the face Hebrew, the eye; of the earth That is, of its inhabitants; that one cannot be able to see the earth It is observable that no living creature multiplies so fast as the locust. It is almost incredible in what swarms they are sometimes seen in some parts. Thevenot gives an account of armies of locusts laying waste the country of the Cossacks. “They live,” he says, “about six months, and lay their eggs in autumn, to the number of three hundred each, which are hatched in the spring following. Such as have been eye-witnesses report, that they have seen the whole air in Arabia darkened by them, in their flight, for eighteen or twenty miles.” “They eclipse the light of the sun,” says Pliny, “in their flight, the people looking up to them in anxious suspense lest they should cover their whole country. They are so destructive that large territories have bean laid bare by them in a few hours, and the inhabitants reduced to famine. They do not spare even the bark of trees, but eat every thing that comes in their way, even to the very doors of the houses.”
