Exodus 9:18-21

9:18 I 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. 9:19 So 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!”’”

9:20 Those of Pharaoh’s servants who feared the word of the Lord hurried to bring their servants and livestock into the houses, 9:21 but those who did not take the word of the Lord seriously left their servants and their cattle in the field.
