Exodus 10:1-5

1The Lord said to Moses, “Go to Pharaoh, for I have hardened his heart and the heart of his servants, in order to display these signs of mine before him,

2and in order that in the hearing of your son and your grandson you may tell how I made fools of the Egyptians and about my signs that I displayed among them, so that you may know that I am the Lord.”

3So Moses and Aaron came to Pharaoh and told him, “Thus says the Lord, the God of the Hebrews: ‘How long do you refuse to humble yourself before me? Release my people so that they may serve me!

4But if you refuse to release my people, I am going to bring locusts into your territory tomorrow.

5They 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.
