3And I will harden Pharaoh`s heart, and multiply my signs and my wonders in the land of Egypt.
4But 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.
5And 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.
6And Moses and Aaron did so; as Jehovah commanded them, so did they.
7And Moses was fourscore years old, and Aaron fourscore and three years old, when they spake unto Pharaoh.
8And Jehovah spake unto Moses and unto Aaron, saying,
9When 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.
