“Seven days passed after Yahweh had struck the Nile. Then Yahweh said to Moses, ‘Go to Pharaoh and say to him, thus says Yahweh, let my people go, so that they may worship me. If you refuse to let them go, I will plague your whole country with frogs. The Nile River shall swarm with frogs. They shall come up into your palace, into your bedchamber and your bed, and into the houses of your officials 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 officials.’ Yahweh said to Moses, ‘Say to Aaron, stretch out your hand with your staff over the rivers, the canals, and the pools, and make frogs come up on 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. But the magicians did the same by their secret arts, and brought frogs up on the land of Egypt.”
After seven days, Yahweh went to Moses to tell Pharaoh that frogs were going to go all over the place. This time, like last time Aaron stretched out his hand over all the waters of Egypt, and the frogs covered the land of Egypt. Moses seems to have the Nile covered, while Aaron does the rest of the country. However, the Egyptian magicians seem to be able to do the same thing so it appears to be no big deal.
“Then Pharaoh called Moses and Aaron, and said, ‘Pray to Yahweh to take away the frogs from me and my people, and I will let the people go to sacrifice to Yahweh.’ Moses said to Pharaoh, ‘Kindly tell me when I am to pray for you and for your officials and for your people that the frogs may be removed from you and your houses and be left only in the Nile.’ And he said, ‘Tomorrow.’ Moses said, ‘As you say! So that you may know that there is no one like Yahweh our God. The frogs shall leave you and your houses and your officials and your people. They shall be left only in the Nile.’ Then Moses and Aaron went out from Pharaoh. Moses cried out to Yahweh concerning the frogs that he had brought upon Pharaoh. Yahweh did as Moses requested. The frogs died in the houses, the courtyards and the fields. They gathered them together in heaps, and the land stunk. But when Pharaoh saw that there was a respite, he hardened his heart, and would not listen to them, just as Yahweh had said.”
This time Pharaoh asked Moses to stop the frogs the next day. If he did that, then he would let them go. We see some movement. It looks like things are going to be okay. Moses cried out to Yahweh and the frogs died all over the place. However, there still was a bad odor. Normally, there were these frog eating birds in Egypt along the Nile. Anyway when Pharaoh saw that there was a let up with the frogs, he once again hardened his heart, and would not let them go, just as Yahweh had said.
