Exodus 9:16-21

16But for this purpose I have caused you to stand: to show you my strength, and so that my name may be declared in all the earth.

17You are still exalting yourself against my people by not releasing them.

18I am going to cause very severe hail to rain down about this time tomorrow, such hail as has never occurred in Egypt from the day it was founded until now.

19So now, send instructions to gather your livestock and all your possessions in the fields to a safe place. Every person or animal caught in the field and not brought into the house – the hail will come down on them, and they will die!”’”

20Those of Pharaoh’s servants who feared the word of the Lord hurried to bring their servants and livestock into the houses,

21but those who did not take the word of the Lord seriously left their servants and their cattle in the field.
