Exodus 8:11-15

11The frogs shall go away from you and your houses and your servants and your people. They shall be left only in the Nile."

12So Moses and Aaron went out from Pharaoh, and Moses cried to the Lord about the frogs, as he had agreed with Pharaoh.

13And the Lord did according to the word of Moses. The frogs died out in the houses, the courtyards, and the fields.

14And they gathered them together in heaps, and the land stank.

15But when Pharaoh saw that there was a respite, he hardened his heart and would not listen to them, as the Lord had said.
