Exodus 10:14-15
10:14 The locusts went up over all the land of Egypt and settled down in all the territory of Egypt. It was very severe; there had been no locusts like them before, nor will there be such ever again.
10:15 They covered the surface of all the ground, so that the ground became dark with them, and they ate all the vegetation of the ground and all the fruit of the trees that the hail had left. Nothing green remained on the trees or on anything that grew in the fields throughout the whole land of Egypt.
