Exodus 9:20-24

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.

Now the Lord said to Moses, “Reach out with your hand toward the sky, so that hail may fall on all the land of Egypt, on every person and animal, and on every plant of the field, throughout the land of Egypt.”

So Moses reached out with his staff toward the sky, and the Lord sent thunder and hail, and fire ran down to the earth. And the Lord rained hail on the land of Egypt.

So there was hail, and fire flashing intermittently in the midst of the hail, which was very heavy, such as had not occurred in all the land of Egypt since it became a nation.
