Exodus 8:10-15 New King James Version (NKJV)

10. So he said, “Tomorrow.” And he said, “Let it be according to your word, that you may know that there is no one like the Lord our God.

11. And the frogs shall depart from you, from your houses, from your servants, and from your people. They shall remain in the river only.”

12. Then Moses and Aaron went out from Pharaoh. And Moses cried out to the Lord concerning the frogs which He had brought against Pharaoh.

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

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

15. But when Pharaoh saw that there was relief, he hardened his heart and did not heed them, as the Lord had said.
