Exodus 9:19-21

Now therefore send [a message], bring your livestock and whatever you have in the field to safety. Every man and animal that is in the field and is not brought home shall be struck by the hail and shall die.” ’ ” Then everyone among the servants of Pharaoh who feared the word of the LORD made his servants and his livestock flee into the houses and shelters; but everyone who ignored and did not take seriously the word of the LORD left his servants and his livestock in the field.
