12 And the Lord said to Moses, Let your hand be stretched out over the land of Egypt so that the locusts may come up on the land for the destruction of every green plant in the land, even everything untouched by the ice-storm. 13 And Moses' rod was stretched out over the land of Egypt, and the Lord sent an east wind over the land all that day and all the night; and in the morning the locusts came up with the east wind. 14 And the locusts went up over all the land of Egypt, resting on every part of the land, in very great numbers; such an army of locusts had never been seen before, and never will be again. 15 For all the face of the earth was covered with them, so that the land was black; and every green plant and all the fruit of the trees which was untouched by the ice-storm they took for food: not one green thing, no plant or tree, was to be seen in all the land of Egypt. 16 Then Pharaoh quickly sent for Moses and Aaron, and said, I have done evil against the Lord your God and against you. 17 Let me now have forgiveness for my sin this time only, and make prayer to the Lord your God that he will take away from me this death only. 18 So he went out from Pharaoh and made prayer to the Lord. 19 And the Lord sent a very strong west wind, which took up the locusts, driving them into the Red Sea; not one locust was to be seen in any part of Egypt. 20 But the Lord made Pharaoh's heart hard, and he did not let the children of Israel go.

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.
