Exodus 9:17

For this time I will send all my plagues against your heart, against your officials, and against your people; that you may know that there is no one like me in all the earth.

For now I would have stretched out my hand, and struck you and your people with pestilence, and you would have been cut off from the earth;

but indeed for this cause I have made you stand: to show you my power, and that my name may be declared throughout all the earth,

Behold, tomorrow about this time I will cause it to rain a very grievous hail, such as has not been in Egypt since the day it was founded even until now.

Now therefore command that all of your livestock and all that you have in the field be brought into shelter. The hail will come down on every man and animal that is found in the field, and isn’t brought home, and they will die.”’”

Those who feared the LORD’s word among the servants of Pharaoh made their servants and their livestock flee into the houses.
