Exodus 8:11-15

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.
