Exodus 9:13-21

13Then the LORD said to Moses, “Get up early in the morning, stand before Pharaoh, and tell him that this is what the LORD, the God of the Hebrews, says: ‘Let My people go, so that they may worship Me. 14Otherwise, I will send all My plagues against you1 and your officials and your people, so you may know that there is no one like Me in all the earth.

15For by this time I could have stretched out My hand and struck you and your people with a plague to wipe you off the earth. 16But I have raised you up2 for this very purpose, that I might display My power to you,3 and that My name might be proclaimed in all the earth.4 17Still, you lord it over My people and do not allow them to go.

18Behold, at this time tomorrow I will rain down the worst hail that has ever fallen on Egypt, from the day it was founded until now. 19So give orders now to shelter your livestock and everything you have in the field. Every man or beast that remains in the field and is not brought inside will die when the hail comes down upon them.’”

20Those among Pharaoh’s officials who feared the word of the LORD hurried to bring their servants and livestock to shelter, 21but those who disregarded the word of the LORD left their servants and livestock in the field.
