Exodus 10:3-6

3So Moses and Aaron went to Pharaoh and said to him, “This is what the Lord, the God of the Hebrews says: ‘How long will you refuse to 1humble yourself before Me? 2Let My people go, so that they may serve Me.

4For if you refuse to let My people go, behold, tomorrow I will bring locusts into your territory.

5And they will cover the surface of the land, so that no one will be able to see the land. 3They will also eat the rest of what has survived--what is left to you from the hail--and they will eat every tree of yours which grows 4in the field.

6Then 5your houses will be filled with them, 6together with the houses of all your servants and the houses of all the Egyptians, something which neither your fathers nor your grandfathers have seen, from the day that they 7came upon the earth until this day.’” And he turned and left Pharaoh.
