Exodus 9:17-21

Still you exalt yourself against My people by not letting them go. The Plague of Hail

Behold, about this time tomorrow, I will send a very heavy hail, such as has not been seen in Egypt from the day it was founded until now.

So now, send word, bring your livestock and whatever you have in the field to safety. Every person and animal that is found in the field and is not brought home, when the hail comes down on them, will die.” ’ ”

Everyone among the servants of Pharaoh who feared the word of the Lord hurried to bring his servants and his livestock into the houses;

but everyone who did not pay regard to the word of the Lord left his servants and his livestock in the field.
