Exodus 10:5-6
5 They will cover the face of the ground so that it cannot be seen. They will devour what little you have left after the hail, including every tree that is growing in your fields.
6 They will fill your houses and those of all your officials and all the Egyptians—something neither your fathers nor your forefathers have ever seen from the day they settled in this land till now.’” Then Moses turned and left Pharaoh.
