Exodus 8:3, 21

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

For if you do not let My people go, hear this: I will send swarms of [bloodsucking] 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, as well as the ground on which they stand.
