4 But Pharaoh will not hearken unto you, therefore I will lay my hand upon Egypt, and bring forth mine armies, my people, the children of Israel, out of the land of Egypt by great judgments.
5 And the Egyptians shall know that I am the Lord, when I stretch forth mine hand upon Egypt, and bring out the children of Israel from among them.
6 And Moses and Aaron did as the Lord commanded them, so did they.
7 And Moses was fourscore years old, and Aaron fourscore and three years old, when they spake unto Pharaoh.
8 And the Lord spake unto Moses and unto Aaron, saying,
9 When Pharaoh shall speak unto you, saying, Show a miracle that I may know you; then thou shalt say unto Aaron, Take thy rod, and cast it before Pharaoh, and it shall become a serpent.
10 And Moses and Aaron went in unto Pharaoh, and they did so as the Lord had commanded: and Aaron cast down his rod before Pharaoh, and before his servants, and it became a serpent.
11 Then Pharaoh also called the wise men and the sorcerers; now the magicians of Egypt, they also did in like manner with their enchantments.
12 For they cast down every man his rod, and they became serpents; but Aaron's rod swallowed up their rods.
13 And Pharaoh hardened his heart, that he hearkened not unto them; as the Lord had said.
14 And the Lord said unto Moses, Pharaoh's heart is hardened, he refuseth to let the people go.
