Then the LORD said to Moses, "Go in to Pharaoh and say to him, 'Thus says the LORD, "Let my people go, that they may serve me.
But if you refuse to let them go, behold, I will plague all your country with frogs;
the Nile shall swarm with frogs which shall come up into your house, and into your bedchamber and on your bed, and into the houses of your servants and of your people, and into your ovens and your kneading bowls;
the frogs shall come up on you and on your people and on all your servants."'"
And the LORD said to Moses, "Say to Aaron, 'Stretch out your hand with your rod over the rivers, over the canals, and over the pools, and cause frogs to come upon the land of Egypt!'"
So Aaron stretched out his hand over the waters of Egypt; and the frogs came up and covered the land of Egypt.
