Exodus 8:2

1The LORD spoke to Moses, “Go in to Pharaoh, and tell him, ‘This is what the LORD says, “Let my people go, that they may serve me.

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.”’”
