Exodus 8:3; Exodus 8:21

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

21 "For if you do not let My people go, behold, I will send swarms of insects on you and on your servants and on your people and into your houses; and the houses of the Egyptians will be full of swarms of insects, and also the ground on which they dwell.
