Exodus 8:5-11

Then the LORD said to Moses, “Tell Aaron to hold his walking stick in his hand over the rivers, canals, and ponds. Make frogs come up out of the water onto the land of Egypt.” So Aaron held his hand over all the waters of Egypt, and the frogs came up out of the water and covered the land of Egypt. The magicians used their tricks to do the same thing, so even more frogs came up onto the land of Egypt. The king called for Moses and Aaron and said, “Pray to the LORD to take the frogs away from me and my people. I will let your people go to offer sacrifices to the LORD.” Moses said to the king, “Please set the time when I should pray for you, your people, and your officers. Then the frogs will leave you and your houses and will remain only in the Nile.” The king answered, “Tomorrow.” Moses said, “What you want will happen. By this you will know that there is no one like the LORD our God. The frogs will leave you, your houses, your officers, and your people. They will remain only in the Nile.”
