12 Then the Lord said to Moses, "Raise your hand over the land of Egypt to bring on the locusts. Let them cover the land and devour every plant that survived the hailstorm." 13 So Moses raised his staff over Egypt, and the Lord caused an east wind to blow over the land all that day and through the night. When morning arrived, the east wind had brought the locusts. 14 And the locusts swarmed over the whole land of Egypt, settling in dense swarms from one end of the country to the other. It was the worst locust plague in Egyptian history, and there has never been another one like it. 15 For the locusts covered the whole country and darkened the land. They devoured every plant in the fields and all the fruit on the trees that had survived the hailstorm. Not a single leaf was left on the trees and plants throughout 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.
