Exodus 9:17-19

New Revised Standard Version, Anglicised Catholic Edition

¹⁷ You are still exalting yourself against my people, and will not let them go. ¹⁸ Tomorrow at this time I will cause the heaviest hail to fall that has ever fallen in Egypt from the day it was founded until now. ¹⁹ Send, therefore, and have your livestock and everything that you have in the open field brought to a secure place; every human or animal that is in the open field and is not brought under shelter will die when the hail comes down upon them.”’
