Exodus 8:2-7

2But if you refuse to let them go, then I will plague all your territory with frogs.

3The Nile will swarm with frogs; they will come up and go into your palace, into your bedroom and on your bed, into the houses of your officials and your people, and into your ovens and kneading bowls.

4The frogs will come up on you, your people, and all your officials.”

5The Lord then said to Moses, “Tell Aaron: Stretch out your hand with your staff over the rivers, canals, and ponds, and cause the frogs to come up onto the land of Egypt.”

6When Aaron stretched out his hand over the waters of Egypt, the frogs came up and covered the land of Egypt.

7But the magicians did the same thing by their occult practices and brought frogs up onto the land of Egypt.
