Exodus 9:23-25, 29

Then Moses stretched out his staff toward heaven, and the LORD sent thunder and hail, and fire ran down to the earth. And the LORD rained hail upon the land of Egypt. There was hail and fire flashing continually in the midst of the hail, very heavy hail, such as had never been in all the land of Egypt since it became a nation. The hail struck down everything that was in the field in all the land of Egypt, both man and beast. And the hail struck down every plant of the field and broke every tree of the field.

Moses said to him, “As soon as I have gone out of the city, I will stretch out my hands to the LORD. The thunder will cease, and there will be no more hail, so that you may know that the earth is the LORD’s.
