Exodus 9:16-21

16But I have let you live, to show you my power. Then people all over the world will know how great I am.

17You are still too proud to let my people go.

18Look! Tomorrow at this time, I will send a very great storm of hail. Nobody has ever seen hail fall like this in Egypt before now. From Egypt's first day as a country until today, nobody has seen a storm like this.

19Now send your servants out to tell this message to your people. You must bring into your houses all your animals from the fields to be safe. The hail will fall on every person and on every animal that is still outside. They will all die.” ’

20Some of Pharaoh's officers were afraid of what the Lord said he would do. So they quickly brought their servants and animals inside their houses.

21But others did not believe the Lord's message. They left their servants and animals outside in the fields.
