Exodus 8:2-7
2 If you refuse to let them go, I will plague your whole country with frogs.
3 The Nile will teem with frogs. They will come up into your palace and your bedroom and onto your bed, into the houses of your officials and on your people, and into your ovens and kneading troughs.
4 The frogs will go up on you and your people and all your officials.’”
5 Then the Lord said to Moses, “Tell Aaron, ‘Stretch out your hand with your staff over the streams and canals and ponds, and make frogs come up on the land of Egypt.’”
6 So Aaron stretched out his hand over the waters of Egypt, and the frogs came up and covered the land.
7 But the magicians did the same things by their secret arts; they also made frogs come up on the land of Egypt.
