Exodus 10:1-5

1Then Adonai said to Moses, “Go to Pharaoh, because I have hardened his heart and the heart of his servants, so that I might show these My signs in their midst,

2and so you may tell your son and your grandchildren what I have done in Egypt, as well as My signs that I did among them, so you may know that I am Adonai.”

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

4Or else, if you refuse to let My people go, behold, tomorrow I will bring locusts into your borders.

5Then they will cover the face of the earth, so that no one will be able to see the ground. They will eat the remainder of what escaped—whatever is left from the hail—and eat every tree that grows for you out in the field.
