Exod 10:1-2

The Eighth Plague: Locusts 1Then the Lord said to Moses, “Go to Pharaoh; for I have hardened his heart and the heart of his officials, in order that I may show these signs of mine among them,2and that you may tell your children and grandchildren how I have made fools of the Egyptians and what signs I have done among them—so that you may know that I am the Lord.”
