Exodus 8:1 -15
And the Lord spoke unto Moses, Go unto Pharaoh, and say unto him, Thus saith the Lord, Let my people go, that they may serve me. And if thou refuse to let them go, behold, I will smite all thy borders with frogs: And the river shall bring forth frogs abundantly, which shall go up and come into your house, and into your bedchamber, and upon your bed, and into the house of your servants, and upon your people, and into your ovens, and into your kneading troughs: And the frogs shall come up both on you, and upon your people, and upon all your servants. And the Lord spoke unto Moses, Say unto Aaron, Stretch forth your hand with your rod over the streams, over the rivers, and over the ponds, and cause frogs to come up upon the land of Egypt. And Aaron stretched out his hand over the waters of Egypt; and the frogs came up, and covered the land of Egypt.
