Exodus 10:4-6

10:4 But if you refuse to release my people, I am going to bring locusts into your territory tomorrow. 10:5 They will cover the surface of the earth, so that you will be unable to see the ground. They will eat the remainder of what escaped – what is left over for you – from the hail, and they will eat every tree that grows for you from the field. 10:6 They will fill your houses, the houses of your servants, and all the houses of Egypt, such as neither your fathers nor your grandfathers have seen since they have been in the land until this day!’” Then Moses turned and went out from Pharaoh.
