12 God said to Moses: "Stretch your hand over Egypt and signal the locusts to cover the land of Egypt, devouring every blade of grass in the country, everything that the hail didn't get." 13 Moses stretched out his staff over the land of Egypt. God let loose an east wind. It blew that day and night. By morning the east wind had brought in the locusts. 14 The locusts covered the country of Egypt, settling over every square inch of Egypt; the place was thick with locusts. There never was an invasion of locusts like it in the past, and never will be again. 15 The ground was completely covered, black with locusts. They ate everything, every blade of grass, every piece of fruit, anything that the hail didn't get. Nothing left but bare trees and bare fields - not a sign of green in the whole 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.
