Exodus 9:23-24 ▼

23 So Moses stretched out his staff toward the sky, and Yahweh gave forth thunder and hail, and fire went down to the earth. And Yahweh rained down hail on the land of Egypt.

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