Exodus 10:1-5

1Then the Lord said to Moses, “Go to Pharaoh. I have made him and his officials stubborn so that I can do these miraculous signs among them.

2You will be able to tell your children and grandchildren exactly how I treated the Egyptians and what miraculous signs I did among them. This is how you will all know that I am the Lord.”

3So Moses and Aaron went to Pharaoh and said to him, “This is what the Lord God of the Hebrews says: How long will you refuse to humble yourself in my presence? Let my people go to worship me.

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

5They will cover the land so that the ground can’t be seen. They will eat everything left by the hail, including every tree still standing in the fields.
