8:1 (7:26) Then the Lord said to Moses, “Go to Pharaoh and tell him, ‘Thus says the Lord: “Release my people in order that they may serve me! 8:2 But if you refuse to release them, then I am going to plague all your territory with frogs. 8:3 The Nile will swarm with frogs, and they will come up and go into your house, in your bedroom, and on your bed, and into the houses of your servants and your people, and into your ovens and your kneading troughs.
