Pharaoh was not content with merely denying the request preferred by Moses and Aaron. He ordered them to be forcibly expelled from the palace. Then God sent the plague of the locusts announced by Moses before. They ate every herb of the land, and all the fruit of the trees that the hail had left, and there remained not any green thing.
And again Pharaoh sent for Moses and Aaron, to ask their forgiveness, both for his sin against the Lord God, in not having hearkened unto His word, and for his sin against them, in having chased them forth and intended to curse them. Moses, as before, prayed to God in Pharaoh's behalf, and his petition was granted, the plague was taken away, and in a rather surprising manner. When the swarms of locusts began to darken the land, the Egyptians caught them and preserved them in brine as a dainty to be eaten.
Now the Lord turned an exceeding strong west wind, which took up the locusts, and drove them into the Red Sea. Even those they were keeping in their pots flew up and away, and they had none of the expected profit.
