Exodus 7:20-22 is an interesting one.
20 Moses and Aaron did just as the Lord had commanded. He raised his staff in the presence of Pharaoh and his officials and struck the water of the Nile, and all the water was changed into blood. 21 The fish in the Nile died, and the river smelled so bad that the Egyptians could not drink its water. Blood was everywhere in Egypt.
22 But the Egyptian magicians did the same things by their secret arts, and Pharaoh’s heart became hard; he would not listen to Moses and Aaron, just as the Lord had said.
So apparently the Egyptian magicians can turn rivers to blood and create rains of frogs, but they just can’t handle a few lice. But nobody ever said how the magicians managed to change the Nile to blood just after Moses and Aaron had done it! The Bible also forgot to mention how all of the blood was changed back into water.
This reminds me of the fifth plague of Egypt, when all of the cattle die. However God ignores this and kills them AGAIN several times. (Exodus 9:19-20, 12:29)
