New King James Version (NKJV)
Exodus 7
21 The fish that were in the river died, the river stank, and the Egyptians could not drink the water of the river. So there was blood throughout all the land of Egypt.
22 Then the magicians of Egypt did so with their enchantments; and Pharaoh’s heart grew hard, and he did not heed them, as the Lord had said.
23 And Pharaoh turned and went into his house. Neither was his heart moved by this.
24 So all the Egyptians dug all around the river for water to drink, because they could not drink the water of the river.
25 And seven days passed after the Lord had struck the river.
Exodus 8
1 And the Lord spoke to Moses, "Go to Pharaoh and say to him, ’Thus says the Lord: "Let My people go, that they may serve Me.
2 But if you refuse to let them go, behold, I will smite all your territory with frogs.
3 So the river shall bring forth frogs abundantly, which shall go up and come into your house, into your bedroom, on your bed, into the houses of your servants, on your people, into your ovens, and into your kneading bowls.
4 And the frogs shall come up on you, on your people, and on all your servants." ’ "
5 Then the Lord spoke to Moses, "Say to Aaron, ’Stretch out your hand with your rod over the streams, over the rivers, and over the ponds, and cause frogs to come up on the land of Egypt.’ "
6 So Aaron stretched out his hand over the waters of Egypt, and the frogs came up and covered the land of Egypt.
