Exodus 9:18-19

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!”’”
