Exodus 8:15 KJV

13And the LORD did according to the word of Moses; and the frogs died out of the houses, out of the villages, and out of the fields.

14And they gathered them together upon heaps: and the land stank.

15But when Pharaoh saw that there was respite, he hardened his heart, and hearkened not unto them; as the LORD had said.

16And the LORD said unto Moses, Say unto Aaron, Stretch out thy rod, and smite the dust of the land, that it may become lice throughout all the land of Egypt.

17And they did so; for Aaron stretched out his hand with his rod, and smote the dust of the earth, and it became lice in man, and in beast; all the dust of the land became lice throughout all the land of Egypt.
