Then the LORD said to Moses, "Go in to Pharaoh; for I have hardened his heart and the heart of his servants, that I may show these signs of mine among them,
and that you may tell in the hearing of your son and of your son's son how I have made sport of the Egyptians and what signs I have done among them; that you may know that I am the LORD."
So Moses and Aaron went in to Pharaoh, and said to him, "Thus says the LORD, the God of the Hebrews, 'How long will you refuse to humble yourself before me? Let my people go, that they may serve me.
For if you refuse to let my people go, behold, tomorrow I will bring locusts into your country,
and they shall cover the face of the land, so that no one can see the land; and they shall eat what is left to you after the hail, and they shall eat every tree of yours which grows in the field,
and they shall fill your houses, and the houses of all your servants and of all the Egyptians; as neither your fathers nor your grandfathers have seen, from the day they came on earth to this day.'" Then he turned and went out from Pharaoh.
