Exodus 10:3-6

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

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

5They shall 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 escaped--what is left to you from the hail--and they will eat every tree which sprouts for you out of the field.

6Then 4your houses shall be filled and 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 5came upon the earth until this day.’” And he turned and went out from Pharaoh.
