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 to 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 in heaps: and the land stank. 15But when Pharaoh saw that there was respite, he hardened his heart, and hearkened not to them; as the LORD had said.
