Exodus 8:21-24
For if you are not going to let My people go, behold, I will send swarms of flies on you and on your servants and on your people, and into your houses; and the houses of the Egyptians will be full of swarms of flies, and also the ground on which they live.But on that day I will set apart the land of Goshen, where My people are living, so that no swarms of flies will be there, in order that you may know that I, the Lord, am in the midst of the land.I will put a division between My people and your people. Tomorrow this sign will occur.” ’ ”Then the Lord did so. And thick swarms of flies entered the house of Pharaoh and the houses of his servants, and the land was laid waste because of the swarms of flies in all the land of Egypt.
Exodus 8:2-15
But if you refuse to let them go, behold, I am going to strike your entire territory with frogs.The Nile will swarm with frogs, which will come up and go into your house, and into your bedroom and on your bed, and into the houses of your servants, and on your people, and into your ovens and kneading bowls.So the frogs will come up on you, your people, and on all your servants.” ’ ”Then the Lord said to Moses,“ Say to Aaron,‘ Extend your hand with your staff over the rivers, over the streams, and over the pools, and make frogs come up on the land of Egypt.’ ”So Aaron extended his hand over the waters of Egypt, and the frogs came up and covered the land of Egypt.However, the soothsayer priests did the same with their secret arts, making frogs come up on the land of Egypt.Then Pharaoh called for Moses and Aaron and said,“ Plead with the Lord to remove the frogs from me and from my people; and I will let the people go, so that they may sacrifice to the Lord.”And Moses said to Pharaoh,“ The honor is yours to tell me: when shall I plead for you and your servants and your people, that the frogs be destroyed from you and your houses, that they be left only in the Nile?”Then he said,“ Tomorrow.” So he said,“ May it be according to your word, so that you may know that there is no one like the Lord our God.The frogs will depart from you and your houses, and from your servants and your people; they will be left only in the Nile.”Then Moses and Aaron went out from Pharaoh, and Moses cried out to the Lord concerning the frogs which He had inflicted upon Pharaoh.The Lord did according to the word of Moses, and the frogs died out of the houses, the courtyards, and the fields.So they piled them in heaps, and the land stank.But when Pharaoh saw that there was relief, he hardened his heart and did not listen to them, just as the Lord had said.
