“Then Yahweh said to Moses, ‘Go to Pharaoh and say to him, “Yahweh says this: Let My people go and worship Me. If you refuse to let them go, I shall strike your whole territory with frogs. The River will swarm with frogs, they will make their way into your palace, into your bedroom, onto your bed, into the houses of your officials and subjects, into your ovens, into your kneading bowls. The frogs will actually clamber onto you, onto your subjects and onto all your officials.'”
“Yahweh then said to Moses, ‘Say to Aaron, “Stretch out your hand with your staff, over the rivers; the canals and the marshland, and bring the frogs up over 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” (Ex 7:26-29, 8:1-3).
