Exodus 8:3; Exodus 12:34

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.

34 So the people took their dough before it was leavened, with their kneading bowls bound up in the clothes on their shoulders.
