Exodus 10:13-15

13So 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.

14And 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.

15For 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.
