Exodus 9:23

Verse Exodus 9:23. The Lord sent thunder] קלת koloth, voices; but loud, repeated peals of thunder are meant.

And the fire ran along upon the ground] ותהלך אש ארצה vattihalac esh aretsah, and the fire walked upon the earth. It was not a sudden flash of lightning, but a devouring fire, walking through every part, destroying both animals and vegetables; and its progress was irresistible.
