Exodus 10:4-6 ▼

4 But if you refuse to let my people go, then tomorrow I will bring locusts into your territory.

5 They will cover the surface of the land so that no one will be able to see the land. They will eat the remainder left to you that escaped the hail; they will eat every tree you have growing in the fields.

6 They will fill your houses, all your officials’ houses, and the houses of all the Egyptians—something your fathers and grandfathers never saw since the time they occupied the land until today.” Then he turned and left Pharaoh’s presence.
