12 Then the Lord said to Moses, "Stretch out your hand over the land of Egypt for the locusts, that they may come upon the land of Egypt, and eat every herb of the land--all that the hail has left." 13 So Moses stretched out his rod over the land of Egypt, and the Lord brought an east wind on the land all that day and all that night. When it was morning, the east wind brought the locusts. 14 And the locusts went up over all the land of Egypt and rested on all the territory of Egypt. They were very severe; previously there had been no such locusts as they, nor shall there be such after them. 15 For they covered the face of the whole earth, so that the land was darkened; and they ate every herb of the land and all the fruit of the trees which the hail had left. So there remained nothing green on the trees or on the plants of the field throughout all the land of Egypt.

Commentary on Exodus 10:12-20
(Read Exodus 10:12-20)
God bids Moses stretch out his hand; locusts came at the call. An army might more easily have been resisted than this host of insects. Who then is able to stand before the great God? They covered the face of the earth, and ate up the fruit of it. Herbs grow for the service of man; yet when God pleases, insects shall plunder him, and eat the bread out of his mouth. Let our labour be, not for the habitation and meat thus exposed, but for those which endure to eternal life. Pharaoh employs Moses and Aaron to pray for him. There are those, who, in distress, seek the help of other people's prayers, but have no mind to pray for themselves. They show thereby that they have no true love to God, nor any delight in communion with him. Pharaoh desires only that this death might be taken away, not this sin. He wishes to get rid of the plague of locusts, not the plague of a hard heart, which was more dangerous. An east wind brought the locusts, a west wind carries them off. Whatever point the wind is in, it is fulfilling God's word, and turns by his counsel. The wind bloweth where it listeth, as to us; but not so as it respects God. It was also an argument for their repentance; for by this it appeared that God is ready to forgive, and swift to show mercy. If he does this upon the outward tokens of humiliation, what will he do if we are sincere! Oh that this goodness of God might lead us to repentance! Pharaoh returned to his resolution again, not to let the people go. Those who have often baffled their convictions, are justly given up to the lusts of their hearts.
