Locusts » One of the plagues of egypt
'For if you refuse to let My people go, behold, tomorrow I will bring locusts into your territory. 'They shall cover the surface of the land, so that no one will be able to see the land. They will also eat the rest of what has escaped--what is left to you from the hail--and they will eat every tree which sprouts for you out of the field. 'Then your houses shall be filled and the houses of all your servants and the houses of all the Egyptians, something which neither your fathers nor your grandfathers have seen, from the day that they came upon the earth until this day.'" And he turned and went out from Pharaoh. read more.
Pharaoh's servants said to him, "How long will this man be a snare to us? Let the men go, that they may serve the LORD their God. Do you not realize that Egypt is destroyed?" So Moses and Aaron were brought back to Pharaoh, and he said to them, "Go, serve the LORD your God! Who are the ones that are going?" Moses said, "We shall go with our young and our old; with our sons and our daughters, with our flocks and our herds we shall go, for we must hold a feast to the LORD." Then he said to them, "Thus may the LORD be with you, if ever I let you and your little ones go! Take heed, for evil is in your mind. "Not so! Go now, the men among you, and serve the LORD, for that is what you desire." So they were driven out from Pharaoh's presence. Then the LORD said to Moses, "Stretch out your hand over the land of Egypt for the locusts, that they may come up on the land of Egypt and eat every plant of the land, even all that the hail has left." So Moses stretched out his staff over the land of Egypt, and the LORD directed an east wind on the land all that day and all that night; and when it was morning, the east wind brought the locusts. The locusts came up over all the land of Egypt and settled in all the territory of Egypt; they were very numerous. There had never been so many locusts, nor would there be so many again. For they covered the surface of the whole land, so that the land was darkened; and they ate every plant of the land and all the fruit of the trees that the hail had left. Thus nothing green was left on tree or plant of the field through all the land of Egypt.
