3 And I will harden Pharaoh’s heart, and multiply my signs and my wonders in the land of Egypt.
4 But Pharaoh will not hearken unto you, and I will lay my hand upon Egypt, and bring forth my hosts, my people the children of Israel, out of the land of Egypt by great judgments.
5 And the Egyptians shall know that I am Jehovah, when I stretch forth my hand upon Egypt, and bring out the children of Israel from among them.
6 And Moses and Aaron did so; as Jehovah 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 Jehovah spake unto Moses and unto Aaron, saying,
9 When Pharaoh shall speak unto you, saying, Show a wonder for you; then thou shalt say unto Aaron, Take thy rod, and cast it down before Pharaoh, that it become a serpent.
