Exodus 10:1-5

1Then the Lord said to Moses, ‘Go to see Pharaoh. I have caused his mind to become hard. I have also caused his officers' minds to become hard. I have done this so that I can do miracles to show him my power.

2In the future, you can tell your children and your children's children how I punished the Egyptians. You can tell them about the miracles that I did among the Egyptians. In this way, you will know that I am the Lord.’

3So Moses and Aaron went to Pharaoh. They said to him, ‘The Lord, the God of the Israelites says this: “You are still too proud to obey me. Let my people go so that they may worship me.

4If you refuse to let them go, I will bring locusts into your country tomorrow.

5They will cover the whole country. Nobody will be able to see the ground. They will eat everything that the hail did not destroy. They will eat any crops that you still have. That will include every tree that is growing in your fields.
