Exodus 8:15

11And the frogs shall depart from thee, and from thy houses, and from thy servants, and from thy people; they shall remain in the river only.

12And Moses and Aaron went out from Pharaoh: and Moses cried unto the Lord because of the frogs which he had brought against Pharaoh.

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.

18And the magicians did so with their enchantments to bring forth lice, but they could not: so there were lice upon man, and upon beast.

19Then the magicians said unto Pharaoh, This is the finger of God: and Pharaoh’s heart was hardened, and he hearkened not unto them; as the Lord had said.
