Exodus 9:13-20

Then the LORD said to Moses, “Get up early in the morning and stand before Pharaoh. Tell him, ‘This is what the LORD, the God of the Hebrews, says: Let my people go, so they can worship me. If you don’t, I will send more plagues on you and your officials and your people. Then you will know that there is no one like me in all the earth. By now I could have lifted my hand and struck you and your people with a plague to wipe you off the face of the earth. But I have spared you for a purpose—to show you my power and to spread my fame throughout the earth. But you still lord it over my people and refuse to let them go. So tomorrow at this time I will send a hailstorm more devastating than any in all the history of Egypt. Quick! Order your livestock and servants to come in from the fields to find shelter. Any person or animal left outside will die when the hail falls.’” Some of Pharaoh’s officials were afraid because of what the LORD had said. They quickly brought their servants and livestock in from the fields.
