Exodus 8:4

2If you refuse to let them go, behold, I will plague all your borders with frogs.

3The river will swarm with frogs, which will go up and come into your house, and into your bedroom, and on your bed, and into the house of your servants, and on your people, and into your ovens, and into your kneading troughs.

4The frogs shall come up both on you, and on your people, and on all your servants.”’”

5The LORD said to Moses, “Tell Aaron, ‘Stretch out your hand with your rod over the rivers, over the streams, and over the pools, and cause frogs to come up on the land of Egypt.’”

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