Exodus 8:2-7

2If you refuse to let them go, I will send a plague of frogs on your whole country. 3The 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. 4The frogs will come up on you and your people and all your officials.’ ” 5Then 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.’ ” 6So Aaron stretched out his hand over the waters of Egypt, and the frogs came up and covered the land. 7But the magicians did the same things by their secret arts; they also made frogs come up on the land of Egypt.
